As @Adam 52 says, this has probably killed off Cloudflare, or at least seriously harmed their rep with their customers.
I very much doubt it. Most probably don't and won't care and many will see it as the right thing to have done. I can't imagine many see it as anything which will affect them unless they were planning on espousing views which people would find objectionable.
That Cloudfare is on a slippery slope is a fear much more than a certainty. One doesn't jump overboard merely because there looks to be an iceberg on the horizon.
The sky isn't falling.
