the deliberate app-store-ification of all things computer is also designed to keep people from asking those questions -- just download in and install, pleb.
it's why the Zoomers can't email attachments or change file types: all of the computers they grew up with were designed so they never had to understand what happens under the hood.
People can't be knowledgable about everything. There's just too much information in the world, and too many different skills that could be learned, and not enough time.
A carpenter can rely on power tools without understanding fully how the tools work, and it's fine, as long as the tools are made to safe standards and the user understands basic safety instructions (e.g. wear protective eyewear).
To me, making sure that apps don't screw with people, even if they don't understand how the apps work, is roughly the equivalent of making sure power drills are made safely so they don't explode in peoples' hands.
Most people couldn't tell you how their furnace or water heater works, or flush toilet (siphonic effect).
... and this is not what I was referring to either.
Less handholding -> more learning... but even then, what I meant is that you do not have to be knowledgeable to know that your "private messages" are not really encrypted and can be read by the admin (in case of forums, for one), and so forth.
