Monopoly is not a necessary condition for antitrust case.

Just as well! Oligopolies are almost as bad as monopolies, for rent seeking and stifling competition.

I don't know about US law, but EU competition law is concerned about “significant market power” and not (just) monopolies.

When talking about modeling oligopolies and monopolies, often oligopolies have worse results.

We need more antitrust on everything. Things are not working if consumers have no choices in practice. "Support Nestle or just never purchase any snack or drink," isn't a real choice.

It also isn't a reality, and if it was, it would be a monopoly, and it would be dismantled.

If you view $1000 iPhones and $200 Androids as the same market, yes. If you view them as different markets because no one’s picking between the two, Apple has 75% market share in premium phones and Android has 100% market share (I do not consider Jio flip phones as a real competitor) in non premium phones

honestly, I don't think it would happen again even if a platform did rise to that level of marketshare
