A lot of companies intentionally do not utilize Cloudflare (or other like-typed providers) for varying reasons. Be it legal, privacy, datamining concerns, company decision, network stack 'issues', existing infrastructure already handles the needs, or even financial burden. There is nothing wrong with not using Cloudflare. I don't understand the tin-foil statement gif.
As robust as Cloudflare is, they
do add another 'cog to the wheel', which means another potential point of failure. The same applies to 'cloud hosting' such as AWS, Azure, GCloud, etc... you're now fully reliant on their uptime/connectivity guarantees.
As for me, I finished implementing
Anubis this morning on just about all websites that I manage (not all of these are Xenforo or forum related), and I've literally shut the door on all of these abusive LLM/AI Scrapers. The only virtual machines on my side of things are now just the load balancers/ingest servers and reverse proxy servers delegating, checking and terminating requests at Anubis. Nothing bot-like is making it to the actual websites, it is actual users and friendly search indexers hitting the backend now.
Self-hosting stuff, and learning the ins and outs of your software and hardware limitations and potential is huge in this day and age. A lot of companies are moving their entire stack 'to the cloud' without having optimizing their websites or web services. That becomes costly, quick. Cloudflare is no different in that instance when you're a large company/corporation.
