That is not even remotely close to same thing, this is about an Apple site controlling content on their site. So no you're still wrong this is not a 1st issue. You might want to read through the full info before claiming this as your example, cause again it's not even close to the same thing.
I knew what I was citing. As I stated from the beginning...
Sure, the first amendment doesn't apply to private institutions in MOST CASES, but it has been held with physical locations that the first amendment does apply to "public square" situations. e.g. shopping malls can be forced to accept the right to assemble and speak.
In Marsh it was decided that the first amendment was applicable to private property. In that case it was a "company town," the court ruled that they were in effect operating as a municipality and thus were subject to the same protections of free speech. That set precedent that first amendment protections apply to the "public square" regardless of whether that physically exists on public or private property. That was later built upon by the Warren court to apply to other private property such as malls (I can look up the case if you really want me to but again I don't make things up). There have also been various state supreme court rulings to the same end (I know California ruled in favor and I think Colorado as well, I'm sure there were others).
It's a fact.
