I’m not playing at anything. Not sure why you have such a defensive tone here.

I’m trying to establish what other industries are “essential” so I can try and understand how we regulate such industries and in what ways they are similar to the discussion here about Apple. If grocery stores are essential for example does that mean they should have to stock competitor store brand products if the competitor want to sell at that store? If I live in a town with only one grocery store and I want to pay with Bitcoin should they have to set up that payment mechanism? Should they have to accept all payment mechanisms? There are lots of questions here that you can open up that draw parallels with Apple here w.r.t being “essential”.

Not everything that is essential should be regulated the same just because they have this factor in common. Stop being so dense. A market being essential simply means that optimal outcomes in that market are very important, so regulation is more justified if that market is a failure (such as a duopoly).

One of the many differences is that the duopoly of Apple and Google in mobile markets is effectively unbreakable without government regulation. Today there is no amount of billions you can spend to break their moat. In contrast, grocery stores are highly competitive because they don't have insurmountable barriers to entry. Anyone can lease retail space and sign up with a distributor. There are lots of independent grocery stores operating in many towns.
