Some day we’ll get there. Feature-wise Mastodon is already far ahead from others.
However, I am not really sure what the end goal is here about should we have the most people here or not, I personally think people should give a shit about ethics. The best possible future is that we can both exist, if the commercial social media connects to the Fediverse (Threads, Bridgyfed/Bluesky, Tumblr), we can have a choice.
