That is not the definition on a monopoly.

And if the question is of "its only fair that govt gets a say", then its a question of what Govt says fairly.

If your goal is user freedom, then Apple is the only eco system that is actually pro user, compared to the alternative (Android).

In which case, Govt should be tearing into Android/Google and all advertising driven/invasive platforms.

Govt would have to advocate that Android be out of Google's purview, or all mobile OS dev be separated.

The issue isn't Apple. Its Economics.

We can call it “exerting their power in unrelated markets” as well.

Apples market share is less than Android. Your argument is like saying Amazon is a monopoly in the kindle store.

Some folks are just power hungry and like to wield force unnecessarily.

This but also because of the size of Apple's market. If they sold 1000 phones per year nobody would give a f... about their commercial practices. In the USA apparently Apple is bigger than Android, so about phones Apple is a larger monopolist than Google. In the EU, not as much but still a relevant one.

Android has a 66% market share in the EU, and ~55% in the US - which it gained only recently (~2021/22). Otherwise Android has had the largest share globally.

By definition, A monopoly force does not have a 33% or 50% market share. It has full control.

If you want, you can switch. If you want, you can use products that are NOT locked to a vendor. You have Dropbox, you have obsidian, email - any number of tools that are not vendor locked.

If you want a phone, you can take many of the comparable or superior phones in the Android ecosystem.

This is being phrased as a goal for "User Freedom". If a user wants the freedom to have a locked ecosystem, where they are the actual paying customer, so what?

Any absolutist user freedom argument has to also deal with users who dont want that freedom.

If this is about meaningful freedoms, then the threat is revenue models. There is no reason the Apple ecosystem should outperform Android - yet it does.
