I strongly encourage anyone who finds Meta's repeated crappy behaviour objectionable to delete their accounts on Whatsapp, Instagram, Facebook, etc. Or, at least, to delete as many as they can get away with, given their personal constraints and obligations, and otherwise minimise as much as possible the interactions with this company.
Personally I do somewhere between one and three strikes with companies. Of course I still must use certain things at certain times, but generally a lot of them can be avoided if you develop the habit of looking for other solutions. It's great fun, actually, once you accept the challenge.
It's only a small action, but it's good on a personal level to practice any kind of resisting.
