AB2012: There was another similar recent thread like this. Post #5 should answer your question
No, it doesn't, because that's not a post from a GOG employee, much less an official statement.
Moreover, the recent Caligula thread shows evidence that GOG sometimes selectively cherrypicks to do special things for some of its customers, but not for others who are in the exact same situation.
In other words, just because the situation applied to poster #5 that you cited, it doesn't necessarily mean that it would also be applied to other GOG customers.
That's presuming poster #5 was even telling the truth (I'm not saying he isn't, but ultimately, we have no way to know 100% for sure whether he is or not).
So my point is, the only real answer to this question would need to come a GOG employee, who states an official GOG policy that they guarantee to apply equally to every customer.
