The difference is that nobody complains and most people agree when you talk smack about Amazon, Google and Microsoft. The general consensus is that they're big, dumb and knowingly evil, and most of the time their actions can be explained by that.

When we talk smack about Cloudflare, such as about their hosting of phishing, their underhanded DoH stuff, their complete lack of abuse handling, et cetera, lots of people come to their defense and make excuses for them.

You can like a company's product and still think the company is big and desires to be evil, but there's an emotional component for some that makes "us versus them" knee-jerk reactions more compelling than, "hmmm... is this correct?" evaluations.

I don't think any of these Cloudflare apologists would try to argue on facts that Cloudflare isn't trying to be a monopoly, isn't trying to recentralize the Internet, isn't marginalizing the rest of the non-western world, isn't trying to establish dependencies that people and companies can't easily escape, but if they did, that'd make for some interesting discussion.
