Apple

Still don't understand with those mentality that hates anything that against Apple's decision. Like, what's wrong with having more option? Mac already has this for decades and is that becomes a disaster I don't think so?

"BuT hoW aBouT tHoSe tEcH iLLiTeRaTe pEoPLe" you, as someone who understands tech, should teach them, to not install anything outside App Store. It ain't that hard. It's not my fault if you're too lazy to do that.

And finally, this side loading can gives me much more positive impact. First, no more Safari-based 3rd part browser. I can finally install a real Chrome that based on Blink, or a real Firefox that based on Gecko. Second, I can install some older games/apps that's no longer available on App Store (literally also some advantage of having a Windows device/Android, you can run old apps on it). And last, emulators, baby! Can wait to use my iPad Mini as some Switch or PS3 emulator. Don't forget about FOSS too, but I won't mention it here.

What are you waiting for? Piracy? Hahaha but no, that's not the main reason why we loves side loading.
