I’ve reclaimed many a PC for folks like you described. So clogged with bloatware, trackers, adware, etc., that the machines could hardly run. Just excruciatingly slow experiences for their owners. Most folks don’t know anything about machines or software. Microsoft’s dominance illustrates the point.

Folks go ignorantly (no offense) where they’re told. They just don’t know better and get prayed upon as a result.

Every one of them knows things I don’t. It’s just that computers are a black box to them.
