Because it's crazy to think that the two dominant app stores are going to have policies that exactly match people's needs, and that they'll implement those policies competently.
Syncing files with Syncthing is no longer possible on Android because the Android team won't fix the performance of storage access framework, for example. This is 100% on Google, not Syncthing.
But I can still use SyncThing-fork because it's on FDroid. Similarly for the Fossify apps, Quillnote, KeepassDX, Privacy Browser, and dozens of others.
Apple will never put in the effort to make a community that thrives on sharing open source apps that are not profit driven. It's simply not in their DNA. And I don't want to have to live in a world where every developer that wants to make a mobile app has to pay a tithe to the overlords of Google and Apple. They will always claim that they're fixing security problems by acting as an intermediary, but there's no way for them to do that without replacing my choices with theirs, and nothing in Google's or Apple's decision-making history indicates they're better equipped to make decisions governing my machines than I am.
So why would a normal person want to sideload? Because they don't want Google and Apple telling them what software they can install on devices they purchased.
