His grand vision remains to leave Mastodon users in control of the social network, making their own decisions about what content is allowed or what appears in their timelines.
I don’t use Mastadon cause I don’t care for micro-blogging, but nevertheless, I like this.
I think you’re making a much bigger deal of the federation issue than it actually matters in practice.
Yes, some users who run their own server with very few other users do face this issue, but it can usually be dealt with without much effort. If they go and follow 200 users on 20 different instances, then they’ll most likely get followed back by someone on 90% of those instances. It’s not that much effort. I now and then you see one of these users making a “please boost and follow for federation” post to get them kick started.
But also, that situation is for techy nerds anyway. Normy users are not going to be setting up their own instance, 99% of them will be joining a populous instance, and so will have good federation with most of the network immediately.
