I agree with both you and the person you’re responding to.
One remembers that during the vast stretch of time that Cloudflare wasn't offering the new whiz-bang service, one was doing just fine in one's endeavors.
If one is fine with CloudFlare being the MITM for most of the Internet, then this doesn't matter at all to you. But if that or any other aspect of how CloudFlare does business and what their capabilities allow them to do concerns you, then that's how one begins.
Do you want the pain now or later?
