If you think about how many people use proprietary Android by Google, it is exactly comparable.
Comparing numbers is pointless here. Fact is that GPL has more conditions when you’re allowed to use and modify the code. More conditions means more restrictions. And this means, less freedom.
It means less freedom for developers but has proved that it provides more freedom for users. Does MacOS have an open source version? No but ChromeOS and Android do (ChromiumOS and ASOP respectively). Even when companies make a proprietary fork of Linux they still contribute massively in terms of code, not just money.
