Perhaps I also didn't make myself clear enough about one more aspect.
Even with store-bought Speccies, people could repair them themselves. Maybe replace a chip or a capacitor or a resistor or a transistor. It was as opensource as it could get. x86 came with modularity, but the overall architecture already was much more complex _and_ individual components could not be just repaired at home anymore. Corporations took the monopoly over these things. They told people didn't need it. And now, people are being fed with monolith touchscreen bricks with zero repairability (+ all-on spyware) and they don't ask any questions why.
The software side of things is even worse, but remember it started when IBM+M$ mafia took over.
