Why is that relevant? Like I genuinely don't understand this incabability to imagine people just...interacting via a medium, and that it is ok for not everyone to be on a single platform. Not everything is about shareholders and creating another megacorp that can ruin my experience as fast as possible.

Sure, some people are not tech literate enough to use a platform like Mastodon, but that is perfectly fine, there are more than enough options for them. Also yes, Mastodon isn't the right platform for people that mainly want to sell you something or 'build their brand', and that is fine too! (certainly a plus for many)

Meanwhile every relevant (as in: information and tweets I actually appreciated, compared to a ton of accounts I followed, but were just rather 'low effort' content I don't exactly miss) account I followed on Twitter is now on Mastodon. So all I need to stay and be happy on Mastodon is for it to not lose those users again, and slow growth is a plus.
