We paid for it. We want it. If you pay for a lifetime supply of...jerky...and i tell you after half a year that we dont want to give you any more, you should be refunded in some way.

What I really don't want to see, though is just another lobby shooter, like Dust has become. As part of the EvE universe, Dust on PC (DoPC) should be a sandbox, like EvE, were battles aren't scheduled, don't start and finish according to some sort of rules, are part of the EvE war system where appropriate, and otherwise, just generally part of the PvP world of EvE. Battles should EXIST wherever and whenever two or more players decide to duke it out, and there should be the scope for more people to arrive on either side to make it as even or as one-sided as those people want. This is what EvE is about, not the stylised battles of Dust.

The nature of the EvE universe is persistence...

No there's no such contract, other than the EULA, but there is a reasonable expectation that if you pay out money for something you will get what you paid for. If that's "unlimited", "infinite", or any other permutation of the infinity symbol that's against all BPOs then you should expect to be able to keep using it, at least in the EvE universe, for as long as it exists. EvE will shut down eventuatlly, one day, maybe, perhaps after a few generations of new players have passed through, perhaps, just maybe. But until then, if you've paid for a BPO, a skin, or anything else that's supposed to be perpetual, we should have access to it.
