Because they don't want to devalue their game by letting their game get bundled and keys to be resold on the gray market when the keys supposedly were never meant to be included in this kind of bundle in the first place? Really, I don't think their mistake was invalidating keys, it was not disclosing how the

up happened in the first place. They've told us that there was a misunderstanding between them and BS, but no further details. Maybe there's some sort of NDA in whatever contract they signed which keeps them from speaking up, but it's hurting them too much in the long run. If it were me I'd disclose that info to the public even it it meant no future business with BS. I'm pretty sure most people would back off if they knew what the exact circumstances were, people love to white knight devs if they see them as the victim, but in this case it ain't happening much because we're lacking crucial info, which is causing lack of trust in the dev and BS.
However, if it was more the dev's screwup than BS I can understand why they don't want anyone to know, in which case no one would defend them and it would cause more of an outrage than what we're seeing now. Maybe they're keeping quiet for that reason, who knows. Honestly if I had bought the bundle and held off on activating keys or held off on buying the bundle period I'd be pissed too, but I have a habit of activating all keys right after I buy bundles. This should be a lesson for the future, activate keys ASAP and don't hold off on buying higher quality bundles if you're interested in the games (looking at you Bobby!). Oh and this could potentially create bad PR for BundleStars as well if they don't do anything to compensate for the situation. Lowering the bundle price by 50 cents isn't doing shit for the consumers lol. They need to make an announcement ASAP if they want to salvage their reputation.
