That's interesting although from a quick skimming it seems that these studies are focused on the activity of the bot accounts. This might give a hint on their relevance but due to the fact that their activity is probably above average it doesn't tell much about their percentage of accounts (in absolute numbers). So I am not sure if there is a studies that shows that something near 50% of accounts would be bots. The number is huge and that's why it is interesting for me to see if it is true and how could we determine that. But I also don't think that the blocking change here would affect signal to noise ratio. You still cannot engage with accounts who blocked you but can see their public posts which you could do by logging out (before X required account to show tweets) and create alt account for that. Blocking access to the already public posts/tweets didn't make sense anyway. And I don't think this is even restricted to X or any particular website.
