They admit to blocking tweets from people's timelines -- even though those people signed up to be a follower of that account, meaning they want to see those tweets. They claim that this just makes it a "little harder" to see those tweets.
Try a lot harder -- the whole point of following someone is to get their tweets to show up in your timeline, for convenience. Yes, you could just go to their account and read their tweets. But that defeats the whole point of following someone -- following makes the appearance of those tweets automatic from your own home account.
They're doing this, they say, to "reduce complaints," but how can someone who signs up specifically to follow an account have a complaint about seeing the tweets they signed up to see in their timeline? The truth is, leftist complained about certain accounts and they don't want people who want to read those accounts to be able to read those accounts.
How does blocking my tweets from their accounts help the leftists who are not following me "avoid harm"? They already are avoiding harm -- most leftist have block-lists that block tens of thousands of people.
They don't see my tweets already. They just don't think anyone else should, either. And twitter agrees. And yet Twitter continues to falsely advertise itself as a neutral forum dedicated to the principles of free speech. They say they've reduced complaints in this way. Sure-- given that leftists are the ones constantly complaining and reporting people to Twitter, for the precise reason to get those people banned or shadowbanned , then yes, doing what the leftist censors want you to do would "reduce complaints.
