Can we please talk about what we do from here on out? How do we make the best of this situation?
The obvious first step is abandon ship.
If you're not willing to do that, then the best thing you can do as an artist is to branch out to other sites and establish separate fanbases from the ground up while FA is in its transition period. That way if/when something actually does go tits-up, you have something to fall back on in the meantime while everyone reflects upon their life choices.
If possible, have and link to a "business card" page with your contact information and links to other galleries, with nice-to-haves like commission info/examples as optionals. Encourage any watchers you have on FurAffinity to watch you elsewhere, and make it a point to keep all of your galleries up to date - If this means choosing only one or two extra galleries, then so be it. Don't neglect these! If it comes down to a mass exodus for any reason, your dedicated watchers will take comfort in knowing that they won't have to figure out where you're active, and wherever they eventually settle, they'll be able to access your art.
That's kind of a doomsday scenario, but it's still a good idea to branch out as people begin to find the new ownership distasteful. While some are leaving now, others are cautiously branching out and others still are remaining where they are. As time goes on, the more artists and users who branch out, the less likely that any negative effects of the acquisition will affect you, or at least, not in a catastrophic way.
