I believe that Stallman is correct in most of what he says. When he started his movements the threats were lower than there are now. But looking at the current state of the industry things are scarier than I ever imagined to be 10 years ago. People cannot even imagine how much data is collected from them each day. And the simplest way to collect data is to sell people phones, and make them install apps instead of letting them use the site (with potential ad blockers).

I've made some experiments on my phones (bot Android and IOS), and you would surprise how many of the apps are "calling home". Because those apps are closed source, God knows what information they are sending back to their servers.
