In my experience this doesn't really end whether it's a closed product or not. If you're wiling to give free IT support, people will take it, as it's likely way faster/better than calling whatever support may or may not be offered by the company.
> Will that be possible with an open platform where anyone can install anything?
I can't see why these have anything to do with each other? If your brother goes out of his way to install a bunch of stuff and breaks everything, how can you possibly blame the system and not your brother?
