> The LGPL gives end users the right to replace the LGPLed part with a modified version, and users presumably cannot alter parts of a downloaded Unity app. You can use LGPL software on a multitenant mainframe system, where you don't have access to modify installed software. This was a well known use case in the 80s and 90s, so this doesn't seem appreciably different. The LGPL doesn't seem to require you as a software developer to ensure that the user can run the modified software on the same system on which the App Store version is run, mainly it's to make the source code available so they can, in principle, create a modified version that they can run somewhere.
