In my country, iOS are more than 50% of the market. I haven't been able to find any EU-wide numbers though, which are the important ones in this case.

This fine isn't about monopoly. But Google:

- has required manufacturers to pre-install the Google Search app and browser app (Chrome), as a condition for licensing Google's app store (the Play Store);

- made payments to certain large manufacturers and mobile network operators on condition that they exclusively pre-installed the Google Search app on their devices; and

- has prevented manufacturers wishing to pre-install Google apps from selling even a single smart mobile device running on alternative versions of Android that were not approved by Google (so-called "Android forks").

The law should be the same for all companies and should not depend on which companies are monopolies.

if we are comparing to the microsoft case apple does have a monopoly. microsoft was not found to have a monopoly on computers in general. it was specifically found to have a monopoly on intel based computers. Apple has a monopoly on A9, A10, A11 based computers. A 100% monopoly

Android does not have a monopoly either. You can buy an iPhone.
