AFAIK they would get the info “which user said what”. The source would be what ever instance you are from tho, not your own ip. So the owner of a instance knows as much as everyone else.

I think they meant your info being sold on dark web markets, not your behaviour on the dark web being sold.

I am not sure as well, but maybe they meant “maybe an early and public disclosure increases the urgency of the fix for the developers”?

Hmm, afaik florisboard doesn’t support word suggestions at all right now. You can read up on it a bit on github but to make it short: the main dev is struggling with creating his own performant word suggestion algorithm.

Do you mean different characters/local keyboards, or different dictionaries?
