Of all the chatter around anti-trust, has anyone broached the app store and apple’s monopoly on iOS software? I am using the term in a colloiquial, non-legalistic sense. My fear is that politicians are invested in tech stocks, like the rest of us and pretty much anyone with a mutual fund, so they are unlikely to act in a pro-consumer manner.
