> But to use that app store you usually have to agree to a TOS that prohibits things like redistributing and reverse engineering. LGPL has it a requirement that the application needs to be distributed in a form where you can replace and modify the LGPL bits. Either via dynamic linking or separately-distributed object files. I'm not sure how you could be considered in compliance with this when the development environment for consoles is an expensive devkit you have to sign an agreement for and the SDK/APIs etc are trade secret. At the very least, I imagine a court would take a very dim view of "well we technically shipped object files in this encrypted container that you can't read or Nintendo will sue you up the ass". If Unity didn't get an exception license for their LGPL bits, then them and pretty much every indie dev that has shipped on console is violating the license. Bonus points for the fact that the termination clause on *GPLv2 is basically one-strike-and-your-out, so they would have to individually go to each LGPL library Unity touched and beg for forgiveness before ever using those libraries ever again. On iOS, any iCloud account can get a development profile set up to build and run code signed for your device. And on the App Store you can write custom EULA language that says "any activity required to exercise your rights under LGPL is explicitly allowed, App Store TOS not-withstanding." The biggest problem is just getting access to the object files and assets in order to relink the app. iOS application binaries are encrypted, and app bundles, while not encrypted, are a pain in the ass to get a copy of on a real desktop OS where the developer tools can run. For a fully FOSS app, you can just link to a Git repository to satisfy the GPL copyleft, but I doubt proprietary developers want to distribute a whole unlinked copy of their code just so you can link it in. There was a problem with VLC on iOS a decade ago, but it mainly has to do with the fact that Apple wants team accounts to be verified with DUNS numbers. VLC is a nonprofit, which apparently made it a pain in the ass to get a DUNS number; but that was fixed a long time ago and VLC is on the iOS App Store.
