It feels almost inevitable that all the major platforms will get compromised in some way, especially as they grow in features and thus attack surface. I can only imagine the magnitude and persistence of attacks on these kinds of platforms. Even if it's possible for them to be technically sound, all it takes is a bad human to spoil all the hard engineering work.

I wouldn't trust sensitive data on any of them, and with the way advertising tech and governments treat privacy, I'm not sure technology has a bright future in that regard. I would sooner write down a secret on a piece of paper and lock it in a drawer than keep them on a computer.

It's much more practical to have retractable, replaceable secrets, so that you have agency over an inevitable leak of that secret. The way credit card companies handle breaches is a great example, they are very sympathetic to the fact that cards get stolen.

I don't lead a particularly interesting life, so it's not really going to stop me from using computers, but on principal it's not very good that we can't trust the devices in our pockets.
