Opponents point out that encryption backdoors might not significantly improve law enforcement’s
There have been cases where police was granted access to the data, but the crimes it was supposed to stop just continued. Not enough personnel, equipment, too difficult or some excuse like that. But if you don’t have enough resources to use the data in a meaningful way, why grant access?
That brings us to the next part, abuse of that data. There have been cases where the access to the data is used to go after organisers of legal protest against environment or labor. Going after certain political parties to harass them, usually left wing, also happens. And there have been cases of police using their access to stalk an ex.
It doesn’t seem to be a net positive.
Probably. There is no user growth anymore at facebook and what’s happening at X shows the network effect can work in reverse. As soon as a certain amount of (high profile) people leave, a lot of their followers go with them, what triggers others to pack up and it’s downhill from there.
