The point isnt the apologists that pop up whereever CF gets mentioned, the point is that they more or less have a built reputation for deceptive loss leader marketing.
Maybe early/MVP product engineers should know better, but CFs own education materials do not teach you to expect that.
If something sounds too good to be true, it probably is.
I have no financial or professional connection to Cloudflare as far as I know and that's partly because I'm not sure I like the way they operate and the level of control over everyone's access to the Web they now have. But if we're going to criticise then I think it should be on a reasonable and preferably objective basis. The claim I challenged appears to be the complete opposite of that unfortunately.
