Honestly if you want sideloading, stay on ios 17.0 or 16.6.1, and wait until TrollStore adds support for those versions

I only updated because I got a new watch and it forced me to update to iOS 17. Losing MDC/KFD and JIT wasn’t worth it

MDC/KFD allowed for a lot of cool jailbreak like tweaks like theming with notifications and no shortcuts banner, dynamic island and iPhone X gestures on older devices, up to 10 apps sideloaded on a free developer account ( up from 3 by default) and a lot of other cool things. Here’s a list of most thing you could do with MDC and KFD

JIT allows for a lot of cool stuff like running Minecraft Java edition, emulating Wii and PS2 games and other stuff. JIT isn’t gone from iOS 17, but Apple changes the way to get it, so people need to reverse engineer it again.

It also runs on iOS and iPadOS

Apple’s GPTK makes 90% of PC games playable.

Yea, but most of the work was done by Valve and the open source community, not Apple

As an Apple user, Apple has much more bullshit. I don’t know much about android, but i think you can unlock your boot loader and install a more private OS like grapheneOS or LineageOS. On iOS you can’t even install a browser that’s not based on webkit (safari’s engine).
