To be fair, this likely only affects millions (if that many) devices -- most people don't sideload apps, and of those that do, most of those users are more than capable of reenabling it through developer tools. The vast majority of Android users don't want to sideload (and shouldn't sideload since they don't know how to validate the safety of the app and they'll sideload anything a website tells them to)
