I'm very much on the side of xcancel and nitter on this one, but I do think it's fair to point out that Twitter is free of monetary charge. It's not free in the sense that you do have to provide some personal information and data to them in exchange for that free account, but it isn't a huge roadblock for most people, however annoying it may be.

Now that said, I sure hope Elon will pivot this and make these services unnecessary. I'm not holding my breath though.
