Interesting article; weird redactions though.
Yes the redactions irk me a bit as well.
Anywho the lawsuit seems to be mostly related to header bidding, not about prioritizing AMP result, because they are faster.. (and yes, I read the part about the Faustian bargain)
The way they’ve played this. This is actually the smartest thing they’ve ever done. Header bidding is slow af.
Luckily there are alternative ways to serve ads apart from header bidding

Also AdSense is not the only ad network you can use, I personally utilize Ezoic that is a 3rd party ad broker that provides the best bid from across dozens of ad networks
Excellent point.
And beyond this, if the antitrust suits are successful (and given the mood of various governments around the world regarding Google's domination I suspect it will be successful), and Google is forced to abandon AMP in search results, it will make most of the debates about whether Xenforo should push AMP pages redundant and moot.
Well the lawsuit seems to be mostly related to header bidding manipulation which I agree is a quite a shoddy thing to do.
The way I see it the following might happen: Google gets a relatively small fine and has to stop "slowing down" the header bidding. Then they pay that fine which will very likely not even compare to what they have earned from their shoddy practices.
Then they will continue to prioritize AMP results, as those are anyway faster. (unless you start comparing oranges to apples..)
Bottom line: It doesn't really matter what happens with AMP, as long as it isn't discontinued (which I doubt, even though it was initially a google product).
We should just focus on increasing the amount of traffic that comes in to our forums. right? or?
I know personally how much my own site(s) have grown by utilizing AMP..
But you can also discard anything I say, as I'm biased and have built an AMP add-on (which will increase your traffic, no doubt) that I will release any day now
All the best, and a happy new year!
