No, but Cloudflare and several other ISPs will not drop you simply because a large volume of people complains. This doesn't work like Twitter moderation. The quality of these complaints warrants not wanting those people associated with you.
Yes they will. This is the example of them literally doing exactly that.
Infowars is literally on Cloudflare right now.
I guess Gab is not villain of the month to be deplatformed today.
The whole point is, Cloudflare still has them as a customer despite all the chaos that has happened with Gab in the past and despite the calls and previous failed attempts to deplatform and wipe them off the internet, they are still there using Epik, HE and I predict that KiwiFarms will follow suit.
Until the next time one of them becomes the villain of the month, then we'll see the same calls, deplatforming attempts once again.
