Sure, but Cloudfare is where you go when you have already had malicious users causing trouble. It doesn't seem crazy that it would be a huge problem for Cloudfare hosted sites (and as such, the block). Sites that want Tor users should do well and avoid services like Cloudfare, but for sites that don't care it's a very effective way to cut out malicious actors. It's not nice in a freedom sort of way, but for ad supported sites Tor traffic is worthless and there is little incentive to try and cater towards it.
