Problem is, like 80% of people are on Mastodon, and many features (quote posts being the most obvious one) require the people you're posting to to have the same interaction with the post.

Using the quote post one for an example: If Mastodon never implements quote posts, what's the point? Most people will only see you posting links and it ruins the whole interaction you're looking for, so using another piece of software isn't going to help.

In regards to people disagreeing with decisions that Mastodon makes (such as full text search like this), it's a bit more complicated. Depending on the feature as well, it's possible for the things you don't like about a feature to still affect you, even if your instance doesn't have it implemented. A LOT of people complained about universeodon.com having full text search, and there was nothing they could do about it (other than just blocking universeodon.com).

I'm personally of the opinion that Mastodon should use its success and mindshare to be a little more like what people expect to get people on decentralised services (within reason - we still want good privacy controls and anti-abuse tools), and then other platforms (or instances!) can then take it further when it comes to things like no search, no quotes, etc. for insular and private communities that people want.
