From Apple’s perspective it’s not shitty, it’s part of their brand. Apple products are all about stupid proofing. Its hard to fuck it up, its hard to download a malicious app or virus. Preventing side loading protects people who don’t know what side loading is. Believe it or not that’s the majority of users. Side loading wont effect profits but thats because the large majority of their customer base will never use it. Those of us who want it are a vocal minority trying to screw up their entire business strategy, so of course they won’t give it to us unless they are forced to do so.
