> Why does that suddenly come into question once they have been successful

Because people don't have a choice. If you want to build a successful software as a service offering in 2020, chances are you need to offer apps for it. Those apps have to be available for iOS and Android else they're dead on arrival, especially for iOS.

While Android lets you easily sideload apps (but even that is rarely enough as most users won't deal with that), iOS is a very strict walled garden. You have to play by the rules, and the rules are finicky and vague.

Like in the Hey mail saga, Apple's whim can make or break an entire business. That's not okay.
