Capitalism does not self regulate[...]
Correct, hence "In theory" and "nonsense" in the words surrounding that phrase.
You should try reading Marx and Lenin’s actual writings[...]

There are multiple free audio recordings[...]
Audio is even worse on that front, as I'll end repeatedly tuning parts out and have to go back and listen to those parts again, which just isn't good for motivation.

Microsoft abuses their de facto monopoly to engage in gross invasion of their users' privacy, and continues to try to wrest their users' control of their system from them by altering system settings after updates, and making some settings nearly impossible to change. And that's to say nothing of MS's attempts to turn their operating system into and advertising platform.
