DNS with CDN with WAF is completely different than, DNS provider, WAF provider, CDN provider.
In which sense? Other than that: In your statement you referred to CF as DNS provider, not to CF for their CDN or WAF. Personally, I don't need a different DNS provider than my provider. I don't need a CDN. I would theoretically profit from DDOS protection, but then until now I never had issues without CF. I would profit from a really good working bot protection, but until now it seems that my homegrown one is no worse than CF but rather better (b/c individually tuned to my needs) and the same goes for WAF.
What monopoly for free customers?
A monopoly is independent from if the product is free or not, it only depends from market share. Cloudflare advertises, they would serve 45% of the Fortune 500 companies and statistics show, that they power about 20% of all websites. This would mean, according to your statement
If you're still using another DNS in 2026, honestly, you're running a website wrong today
that 80% of all websites (and 55% of the Fortune 500 companies) are run by blithering idiots. As I said: Pretty bold statement from your side.
Within the reverse proxy market (so their field of business) CF has
a market share of 85% as of 2026 - I'd say this is as close to a monopoly as it gets. We also see, how the world reacts (and how dysfunctional wider parts of the internet are) when CF has one of its many outages. With CF you add complexity to your setup, join a "single point of failure and it will happen" party and terminate your private ssl-connections inside a company that is unter US legislation, so basically the privacy of your users is doomed. If you don't care about all that or consider it unimportant in comparison to what CF offers it might be a valid way to go. Still pretty ignorant to say everyone who sets different priorities from you would be running his or her "website wrong".
Also, Cloudflare has become the preferred choice for fake shops and other illegitimate content and activities (including those offering resident proxies that enable the bot armies, that are the reason why this thread exists in the first hand). They hide their websites and their identities behind behind Cloudflare, making it harder to track and identify them. This has been going on for a long time and is not a rare occurrence but rather the standard. Cloudflare seems to do nothing about it and there is no transparency about those issues from Cloudflare either. So Cloudflare enables and supports malicious activities on the net including those that they claim to protect you from.
Their bot directory and bot radar leaves out all those resident proxies but rather focusses on easy to identify bots, such giving a completely wrong picture about the situation and the effectiveness of their solutions.
Unless CF decided to stop their free tier, then people would just move and alternatives would appear, CF would be no more.
We have seen how "well" this works when companies like Google (including their daughter YouTube), Facebook (including the other companies of Meta), Amazon, Microsoft, ebay, AirBnB, Booking.com and legions others started to misuse their market power as soon as their marketshare was big enough. It did not work at all b/c the monopoly and the amount of marketshare and financial power did leave no room for others to establish.
There are basically three reasons why CF's free tier exists and in fact only one that counts:
• lock customers into their solution early (so that they might rather upgrade to a paid tier later than switch solutions)
• be able to communicate the own solution as the dominating market standard in marketing (which would not be possible w/o their free tier)
• gaining the data from the clients on the free tier. It saves CF a ton of money for establishing sensors that they would have to run themselves and they would still not be able to gain a fraction of the real world data and insights that the users of the free tier deliver them).
The latter is the one huge reason why they do have a massive interest in the free tier. Yet still it is obvious that, being a commercial company, their interest is to provide just enough service quality for people to join / not to leave (so that CF will still gain data) but longterm to limit/lower the quality of the free offering to an amount that more and more people are forced into paid tiers so that CF will increase their profits. The more marketshare they have, the more people see and market CF as "there is not alternative", the more people unlearn or avoid to learn how to deal with what CF offers independently of CF the sooner this will be happening. We already see that CF is trying to establish a marketplace for AI scraping and you can be pretty sure that they will enforce it once it has gained traction. We see that within the free tier protection is limited. We see that, if you enable bot protection in the free tier, it is for one not all that good and secondly that the Google indexing bot is locked out without a choice. For good reasons - but if you want a different behavior you have to go for a paid tier. So it is not that there would be no signs of CF working for their own good rather than your's. They are a commercial company, not white knights and one must be pretty naive to ignore that.
There is the old wisdom in internet commerce "if you don't pay you are not the customer but the product" - obviously this is true for CF as well. And obviously, as many others, they follow the route that made Rockefeller the richest man on earth: Give away the lamps for free and sell the oil that's needed to make use of them.
No, just realism. If you want another Google situation, becoming totally dependent from what a monopolist decides for his own good w/o giving a damn about your needs: Your choice. Just don't act surprised when it happens.
