I wouldn't be so quick to ascribe malice. I can't see anything highlighted here that is factually incorrect, but even if it was: I know Rabble and arcalinea from their work pre-Blue Sky, and I find it much easier to believe that they're simply mistaken rather than deliberately fearmongering. Their task here is to compare existing solutions to each other and to a hypothetical ideal solution. Inevitably, they'll criticise the existing solutions. It's not an attack.
A silly instance of Mastodon for queer folk and non-queer folk alike. Let's be friends!
