I don’t use it, but some government organizations keep doing it. Why on earth they do that, I will never know, but I’m not making an account to read a tweet.

> X needs revenue to continue

I think that's the point

You don't have a choice when cities, counties, or other government officials decide to make announcements on there.

what else is illegal? adblock?

This is just like the ad-blocker discussion and Nitter is just as fine as ad blockers. Sometimes official sources make announcements via services they should be prohibited by law from using, so you need to buy into the sour apple and read these announcements by other means, whether that means using an ad blocker or Nitter. There is no copyright infringement because X does not hold the copyright on the (vast majority) of that content.

Also worth noting: I click on Nitter links but I would never in my life click on an "X" link. When I use Nitter, X loses zero ad revenue.
