I didn't mean in the first message simply knowing the difference between tabs and windows and a few other GUI bits and bobs, those were meant to be an example of a larger point. The larger point being the notion that it's fun and possible to be a combative, pro-active, "liberated" computer user.
The empowerment of computer users is diametrically opposed however to the interests of Apple, Google, Meta, Microsoft, Tesla, Amazon, etc etc. The ideal computer user for them is one who knows nothing, except exactly what they need to know to keep clicking, commenting, sharing, liking, spewing out their personal details, and fishing out the credit and debit cards.
