It's because of the trademark: https://stoat.chat/updates/long-live-stoat

Nevertheless, I don't like the new name either, oh well...

I like this comment though:

Imagine you make a free software project and it runs into trademark issues because people have more money than you to register in more classes than your project.

And then even though your project existed first, they still come after you anyway.

And from that an even more expensive rebranding from this as well.
