Musk makes it hard to follow Kamala Harris on X, while donating 45Million per month to Trump

Yes, and I'm not using xtter, but I'm still being effected by it. As is everyone on the planet.

The thing that makes me nuts is people justify it by, "but it's the only place I can find (person or service)."

Back in my day! People posted their products and services on multiple platforms to reach a broader audience. If the creator you like is too lazy to market themselves, having gotten spoiled on "Xitter will do my marketing for me," then that's on them. Encourage them to post on other platforms in order to reach you.

They are complicit and so are you.

How else is someone going to find out about Biden retiring? Twitter is the official government platform.

That’s not going to move the Twitter userbase with it. Then they’d only be communicating with Fediverse adopters.

How do you solve for example, de-federation with government owned instances ( which I imagine many would do)

Mastodon suffers the same problem as Twitter, if the people in control of the servers don't like it, they get to be arbitrate for their users. The solution is not for everyone to host their own instance as it's just immensely wasteful and complex, and since de-federation is not positively communicated, one can go a very long time before realizing they are getting content filtered unwillingly.

I just don't see how this problem (specific content being blocked) would be solved by the Kamala Harris's campaign team having a mastodon instance.

Nah, the government should leave en masse and say it's because it supports free speech. And post a screenshot of the 1st amendment.
