Waterfox lore - it got acquired by System1 of "Guy Who Runs Three Companies Called Fidelity But Not The Fidelity You Know Probably Doesn’t Care That There’s Already A Company Called System1 That Does That Same Thing As The System1 His SPAC Is Buying. Just saying." 1 and then went private again 2, presumably they bought it back after the stock predictably tanked. Subprime adtech is a strange place.

IMHO should just bring back iceweasel, but what do i know.
