It's not just one instance and not even one frontend existing for what can be described as "fediverse". Decentralization is the whole point.

Everything depends on the instance you're using. Some of them, like mastodon.social, are very active, others are not.

Find a better instance. On the one I use it's 2k characters limit.

Yes, because it's a whole new level of independence. NewGrounds, Myspace and everything you mentioned are centralized platforms, which is practically vendor lock-in, because you're dependent on just one vendor for everything you do on these platforms, while on fediverse, you aren't. Instances are completely (except for showing posts from one another) independent from each other - there's no central "authority" controlling all of them like there would be on a centralized platform. Thousands of them exist for every frontend imaginable, and you can create one yourself.
There is a reason why common people picked Bluesky instead of the fediverse.
Yes, and that is because "common" people became used to centralized platforms and don't bother. That's also why fediverse's main audience is techies.
