That's not a big difference, with Android, because nobody is making any money doing that. It doesn't work.
I didn't mention Windows. I was discussing platforms where everyone takes a 30% cut. You may say this is mere whataboutism, but anyone who reads Hacker News knows that 99% of the anger and attacks on this practice are directed at Apple. Nobody bitches at Google and Sony and Microsoft for doing the exact same thing.
Google gets hit on the privacy front pretty regularly. I guess it depends on the issue. But not to worry, I'm sure there will be plenty of time and opportunity to complain against injustices from all corporations in the future. A significant chunk of early adopters for Apple/MS/Google products were nerds who spread the good word. Its no surprise that issues like privacy, developer freedom and hacker-ethics will drive the conversation against these companies.
And a big difference with Google is that you can sideload or use other stores on Android. And same on Windows, you don't have to use the store.
