What you describe in the first paragraph is not censorship.
There's a whole thing around censorship not applying to private platforms, but even if you argue that the word "censorship" applies to a private entity moderating the content it publishes with its own money (like Hacker News: It definitely moderates content), the thing you describe is still not that kind of "censorship."
Showing or not showing your tweets based on Twitter optimizing for engagement and advertising is not like a government deciding that nobody is allowed to criticize the Dear Leader.
It's actually like a grocery store that promises to stock your product for free, but you aren't Coca-Cola, so you get shitty shelf space and positioning, until you either pay up for shelf space, or build enough demand for your product that the store decides it can make more money giving you better positioning.
Twitter also moderates content in a way that has nothing to do with engagement and making them money. But if you give someone free content, you have to accept them deciding how they feel like monetizing that content.
If you don't like it, write a blog.
