You're making an incredible amount of assumptions. You're assuming people do it by mistake. Maybe their phone is where they have internet access. You're assuming repeated downloads aren't intentional. Maybe they're retrying a failed download. You're assuming this is out of ignorance rather than, you know, the language barrier. You're assuming there's no Wine on Android because it was "never taken seriously", rather than, you know, insurmontable technical difficulties.
Please learn to ask other people why they do things in ways you deem strange. We're not imaginary. We're very real. We all have different knowledge and abilities, and reasons for doing things this way as opposed to that way. Talk to us. You'll be surprised.
(By the way, computer education these days is horrible. People are either thrown into the deep end of the pool and left to thrash, or else taught to press a few buttons in a certain order with no explanation. This causes no end of trouble for everyone involved, but throwing blame around doesn't help. We need solutions.)
