When there were many different app stores to choose from, nobody would be forced to use an unmoderated app store. What happened to individual freedom and responsibility?

I would need to see a widely used and trusted 3rd party store before leaving Google Play became a consideration. I'm interested, but not an early adopter. It's also unclear if any store that reaches this point doesn't institute similar moderation techniques. Scale incentivizes bad actors, which in turn requires good moderation.
