Is that a problem? You could already just view their posts without an account, or create a burner account. Might be a hot take, but I think someone with a public account shouldn't expect to be able to hide it from specific people.
it’s more evidence that X caters more to the blockees than the blockers.
I'm not sure I agree. However, even if it's true, I'm not sure it's such a bad thing. If you're saying something in public and I'm not even allowed to hear it, let alone respond to it, because you blocked me, you have an effective tool to shut down any dissent. This is what I saw on reddit all the time, there were posters who would block anyone who disagreed with them and so the comments sections on their posts would become very skewed.
And just the other day, I said that David Duke endorsing Jill Stein doesn't mean Jill Stein approves of David Duke or anything he stands for. Someone accused me of defending David Duke, and when I pointed out that his was fantasy, they blocked me. So I see people blocking for bullshit reasons all the time.
Lemmy is much the same, even less restrictive because you don't even have to log in to see anything. It's better this way.
