About Tesseract: Admins tend to move exceedingly slowly... but I would guess that at this point given the severity of the breach, most instances might be amenable to at least roll back to an older version before implementation of the hidden shadow list, or perhaps even to switch to using db0's fork that removes it? Except that db0 is also antagonizing especially LW and possibly even calling for defederation from them at some future date, so I could see strong hesitancy to make stronger tie-ins with him at that point, especially given the sensitivity already surrounding the Admiral Patrick issue - so perhaps they would want to simply deprecate it altogether. It is a quite popular one though.

Most of the discussion that I've seen so far is merely bravado e.g. bragging about having made it into the list of shadow-banned users, rather than efforts to move forward to a positive resolution.

So instance admins might welcome such a discussion... perhaps after a cooling-off period first?

However, Tesseract is not a 3rd-party app - it's an alternative front-end UI for Lemmy. So that means then that i.e. it's not up to individual users to change the version offered, and instead is solely under control of each individual instance admin that offers that alternative.
