Android's sideloading limits are its most anti-consumer move

Installing any app I want outside the Play Store was the primary reason I decided to go with Android, despite most of the people I know using iPhones. If I can't do this anymore, I may as well switch and be able to use iMessage and FaceTime with them.

You can still install apps outside the play store, but the developer does need to verify their signing information. Effectively this means that any app you install must have a paper trail to the originating developer, even if its not on the app store. On one hand, I can see the need for this to track down virus creators, but on the other, it provides Google transparency and control over side loaded app. It IS a concerning move, but currently this is far from 'killing' non-appstore apps for most of the market.

Yeah... no. This is normal with desktop computers. Let's stop handholding people. If I trust the source, I trust the domain... I want to be able to install app from its source.

Googles/Apples argument would have been much stronger if their stores managed to not allow scams/malware/bad apps to their store but this is not the case. They want to have the full control without having the full responsibility. It's just powergrab.

And you are completely ignoring viruses, ransomware, keyloggers, the 50 toolbars etc that has been the staple of Windows and before that DOS for over 40 years.

Scam apps are rife in the iOS App Store. But what they can’t do easily install viruses that affect anything out of its sandbox, keyloggers, etc

Sandboxing isn't feature dependent on Apple being a big curator is it? These are orthogonal but not the same issues. I've never said that PCs don't have viruses or that it isn't a problem, only that I should be able to install software from developer I trust if I want to.

I agree let's have sandboxed app instalations on platforms. Flatpak is already going this way. But it looks like big players Microsoft,Apple and Google are gatekeeping app sandboxing behind their stores instead of allowing people/devs to use sandboxing directly.

And then there will still be complaints about Google limiting what apps can do and take away “your freedom”. What happens when a third party app wants to be able to read in other apps internal storage to create a back up solution like iCloud? Should that be allowed? What about if they want to create an app that autocompletes what you type when working in another app requiring key logger like capabilities?

What part of "I should be able to install software from developer I trust if I want to" was hard to understand?

Then you don’t want sandboxing if you want all of those permissions.

Sure I do. I sandbox what I want when I want.
