I'm not sure you've got the hang of this yet. Let me try and clarify it further.

As I understand it, Ovi Store can't legally distribute GPLv2 binaries without providing the source or providing a written offer to provide the source.

If they provide the source directly to recipients of the binary, their obligations are fullfilled. If they don't then the written offer they must provide applies to anyone, not only recipients of the binary, and this applies for 3 years after they stop distributing the binary.

If they don't satisfy these obligations, then they have no licence to distribute the binaries. Ceasing distribution doesn't nullify their prior breach of copyright law though and still leaves them vulnerable.

The only people who can enforce the obligation by suing Ovi Store are any of the copyright holders of the GPL'd code.

It's also my understanding that the GPL (v2) provides only freedoms to me as a recipient of such code, not obligations unless I choose to distribute it or derivatives of it.
