Earlier quoted context omitted.
If you claim something like "John is a carpenter because John is a human and carpenters are humans" and someone points out that your logic doesn't follow (by applying it to some other known non-carpenter human), you can then claim that this doens't prove that John isn't a carpenter, but the point is that the original claim utterly fails to prove that he is.
Where did I assert something similar to your example? It seems like a false analogy. The criticism wasn't even that my logic was flawed but that the same argument could somehow be made to justify any user-hostile action. If the problem in your point of view is that I didn't /prove/ how big of a problem sideloading was then yes, I didn't even attempt to do that. There's a separate subthread on that question.
That's why your logic is flawed. If a construct can be used to "prove" various known-false statements then it has no value in proving anything.

There is no proof of it there either. The most popular platforms (Android on mobile and Windows on desktop) allow the user to load their own applications, showing not only that it can't be a major cause of failure in the market but that it seems to be a characteristic of the player with the most share.
