Key thing is that retailers aren't being forced to do this. That's why it's an "affiliate" program.
If a store is willing to buy back or offer some sort of return policy, that's on the store management. They can do that with or without manufacturer permission. But if they do have a return policy, all this program means is they get to slap a fancy "Dynamic approved" tag on it.
This isn't a big deal. At all.
Fair enough.
