I’m not a lawyer, but I believe that if the Lemmy instance’s ToS indicates where disputes will be resolved, and either the site owner resides there or is an LLC that is registered there, that you could sue Meta in that location.
Meta is big enough that they are most likely conducting business there (even if digitally) and you could also show that the harm suffered was suffered there.
Just be aware that you need a 2230 M.2, not the much more common 2280 size.
