Encrypted apps like Signal encrypt messages in a way that only you and the recipient can decrypt and read. Not even Signal can decrypt them. However it has always been the case that another person could look over your shoulder and read the messages you send, who you're sending them to, and so on. Pretty obvious, right?

What the author and Signal are calling out here is that all major commercial OSes are now building in features that "look over your shoulder." But it's worse than that because they also record every other device sensor's data.

Windows Recall is the easiest to understand. It is a tool build into windows (and enabled by default) that takes a screenshot a few times per second. This effectively capture a stream of everything you do while using windows; what you browse, who you chat with, the pron you watch, the games you play, where you travel, and who you travel with or near. If you use "private" message tools like Signal, they'll be able to see who you are messaging and read the conversations, just as if they were looking over your shoulder, permanently.

They claim that for an AI agent to serve you well, it needs to know everything it can about you. They also make dubious claims that they'll never use any of this against you, but they also acknowledge that they comply with court orders and government requests (to varying degrees). So... if you trust all of these companies and every government in the world, there's nothing to worry about.
