That sounds like the "and the runtime (which means your shipped game)" part?

Nobody in this thread has firmly pointed to LGPL code being linked or used in the iOS runtime in a Unity 2021 or later built game. Having not looked at this myself, I can't say either way, but it is almost certainly wrong to say that the runtime contains otherwise LGPL code that was not expressly licensed or permitted for the purpose by its authors.

The resulting binaries depend on the unity runtime which itself depends on these LGPL components.
