This isn't very actionable advice, though, since there is basically no such thing as a software product that isn't built on somebody else's property. You might think, "Ah-ha, web apps!"

The amount of effort and goodwill, say, Microsoft would need to spend to prevent me from installing $PROGRAM on my computer is significantly higher than the amount of non-effort a single extension reviewer would need to expend to click "no" arbitrarily because they are having a bad day. How would Microsoft do it?…
To its credit (though not everyone agrees), MS has spent a lot of effort making compatibility shims, basically doing other people's work for them, but they have no such obligation.
