"I'm much more fearful of a legal regime that could step in and simply dictate the business operations of a private entity."

Which is so unlike the legal regime that backs up that "private" entity when it uses government granted privilege to keep competitors at bay (such as with patents and insane copyright legislation).

I would be perfectly fine with having their own little private ecosystem where they pull the rug out from under developers -- if they would stop trying to undermine those trying to compete with it via lawsuits, for that would just mean that they would ultimately learn their lesson. But when the government stands behind their tyranny over developers, they never learn.
