Hooking keystrokes, mouse, screenshots on a local machine is what every decent journaling or timesheet app already does, and nobody cares because the file stays on the user's machine. Meta isn't getting dragged because they figured out how to instrument work laptops. They're getting dragged because they're the ones holding the logs, and "just for training" is a promise that hasn't aged well anywhere it's been deployed the last ten years.

Annoying side effect — the genuinely useful version of this, local activity logs you own for your own records, gets lumped in with bossware every time this comes up. Most freelancers and consultants I know would pay for the former. Most of them would quit over the latter.
