I hate Facebook MUCH MORE than the average HN user, but I don't think Facebook can be blamed for this specific instance. If law enforcement asks for data, you have to comply or find yourself in a very tight situation.

However, if this situation can teach us anything, is how important e2e encryption is so important. If a company cannot read your messages, they cannot share them with third parties like in this case.

Of course, I've been saying this for years, but people claim it's fine since they have nothing to hide. You don't have anything to hide, until abortion, contraception, or fornication becomes a crime. Before your religion is banned, or any other similar situation.

Can we please start learning for repeating the same mistakes over and over for decades?
