Imagine if Microsoft did this on PCs. a) prohibiting the installation of non-windows store software (sideloading) and b) insisting that all purchases done via apps give them a 30% cut. I think this is a ridiculous practice on the behalf of Apple.
I fear that macOS is going this way. The amount of hoops to jump through to run third party apps seems to grow with every release.
You literally just right click and open. Hardly a hoop.
Right, until the app needs to access a file, change a setting or do any number of other things.
Is clicking allow when it asks to access your documents folder that crazy? Is that really a hoop not worth jumping through? Those prompts show up after a clean install and on occasion when you install a new app. Those same prompts prevent you from giving ransomware access to your whole FS.
Have you tried running an unsigned app from the internet? There is no "allow" button. You have to go through security menus and whitelist the app. Who knows if that will still be possible in the future.
