I think you gave very good examples. For me, Ticketmaster and scientific journals abuse their position and there should be laws to prevent that.
My disagreement is with the belief that existing anticompetitive laws apply to this situation.
You can't have a successful app business without putting your offering in Apple's app store.
Our existing anti-trust laws absolutely apply here.
Who knows... we'll see I guess. I don't think Epic will win, but I hope something changes because I just really want to put my own app on my own phone and help my customers do the same.
