"Shopping Malls can have Sex Shops."
Why do people find a corner-case of an analogy, and somehow think it negates the analogy?
It's just an analogy.
Of course 'some malls have sex shops' - but obviously, most of them don't.
The vast majority of corps don't want their brands anywhere near porn, sex, guns, politics, hate/contentious speech etc..
Most decent malls are actually selective of who they want in there, and the 'other residents' of the mall have a say as well.
There are an infinite number of places porn/guns/politics can be sold, so that's not a problem, it's just not going to be in a system wherein the other players are wary of it.
It's actually good reason why we need a lot of alternative points of distribution.
I wonder if there should even be some legislation around that, in terms of the kinds of app stores that are preloaded must be more 'open' and that alternative options must be provided very easily.
