I'm not sure why you were flagged. While the OP is responsible for a lack of version control, the distribution channel is very inflexible and something developers have to fight with.

Many other distribution channels provide multiple binaries or versions and let the customer choose which to install.

Apple and Google are very simple and primarily aimed at non-engineer consumers, so it makes sense that they wouldn't allow people to select a version. It doesn't mean that this doesn't suck.

Maybe things have changed now, but as far as I can remember Google Play does let you deploy older APKs. But it's just from the developer side, it's not like users can choose which APK to download.
