Fandoms like to believe that they own the thing they're fans of. And it sucks when someone charges you money for something that's already yours.
Now, few people would outright say that they object to WOTC making money. But, they do get hypercritical over how WOTC makes its money, and object to things that don't merit objection. You get into this bizarre loop, where something that lacks content is deemed worthless, but something with content is deemed an effort at extorting you into buying it so that you can have access to the content inside. We've seen it here.
Person 1: Product X is worthless, its all useless fluff! I hate it!
Person 2: Actually, Product X is going to contain Useful Crunch.
Person 3: They put Useful Crunch in Product X??? Its just extortion to force me to buy Product X in order to get the full game!!! I hate it!
