Parent article: Relicensing VLC from GPL to LGPL
It would seem that distributing VLC in a locked-down app store, where users cannot replace any part of the code once installed, still violates the spirit of the licence, if perhaps not the letter.
LGPL2.1 only talks about use of a suitable shared library mechanism for linking with the Library. It does not give you the ability to replace said library. LGPL3 is different, but that's another story, we are talking about LGPL2.1+ here.
If I downloaded VLC onto an iPhone, and then wanted to exercise my right to modify the LGPLed code, how would I do that?
It's your problem, really.
And how is this any different to plain old GPL?
That part is easy: any application distributed from Appstore includes proprietary Apple's DRM components - and thus such distribution is incompatible with GPL2 (but obviously compatible with LGPL2.1). Note that there are some Android devices which are Apple-style locked down and will only accept applications from one fixed source. That's fine: as long as application itself is not copy-protected GPL is not violated.
