It makes checking the hygiene of apps you use impossible, building them from source artificially difficult and expensive and pushes users towards services with serious flaws like icloud backup.
We could have taught people such things, but there’s no profit in that. We want to maximize the number of people using our devices and our software, so that we get richer, even if it means putting some fraction of these users in grave danger. That’s simply negligence. That it’s distributed across an entire industry doesn’t change the ethics. Selling people tools that put them at risk is much different than sharing foss.
Some things you say make sense, but suggesting that “people” can/should learn how to build from source is simply nonsense. Heck if I had to build my OS I’d stick to a feature phone instead.
