The value of the playstore or appstore doesn't come from the apps on it. It comes from the fact that it is bundled with every single device running the corresponding OS. Any app that wants to be successful has to be on them. Even OEM app stores aren't that widely used. And web apps are often not a choice since some functionality are not exposed to them. So the other comment is still valid.

If we want these companies from abusing their dominance, they have to be either penalized heavily and forced to compensate the victims, or it should be mandated that these devices bundle a trustworthy 3rd party store.
