People are getting all upset at Facebook/Meta here but they were served a valid warrant. I don't think there is much to get mad about them here. The takeaway I get is this:
Avoid giving data to others. No matter how trustworthy they are (not that Meta is) they can be legally compelled to release it. Trust only in cryptography.
There is of course the other question of if abortion being illegal is a policy that most people agree with...but that is a whole different kettle of fish that I won't get into here.
