RE: CloudFlare TOS, Not anymore. They removed section 2.8 from their TOS, so all content can be served through CloudFlare now, as long as it doesn't use the CDN.
I agree with the self sustainability.
I started browsing fediverse a bit back, but there wasn't enough content so I would go back to Reddit (mostly to catch up on news and discussions).
But I'm going to Reddit less and less now as there are more people engaging in fediverse content. I now mostly go back for specific subreddits, but not the general feeds anymore.
