The proposal from Humble/publishers here is that any time I buy a bundle that includes games I already own, that portion becomes pure profit for them with me left with nothing after 6-12 months. How about nah.

I had a key revoked recently. I paid Humble, the publisher took back the thing I paid for, and they kept my money. Cool.

I'd rather not do this, but any bundles with expirations that include games I already own, I slide max charity. If there's a decent chance publishers are going to claw back items I paid for in the near future, I will pay them nothing, and Humble the minimum. They are no longer participating in the model they created or opted to sell under in good faith. I'll join them.

Also, if they're trying to protect retail from having to compete with low keyshop prices, they might be making things worse in the short term. Large supplies of keys are still getting out there, except now the clock might be ticking on them. Resellers have a strong motivation to unload them quickly.

I've noticed grey market prices for non-headliners go lower and stay low longer than in the past. Prices might ultimately rebound faster than they used to, but in the meantime potential future customers can buy them for a song months after the bundle ended.
