Blizzard is in trouble but not for financial reasons. They're still making money hand over fist with WoW and that behemoth will keep lumbering along generating revenue out of sheer momentum.
Blizzard's issue is their IP is stagnant. They've fallen into a cycle of generating revenue from micro transactions and lootboxes. Their big IPs they've managed to kick themselves in the ass when it comes to storylines. Warcraft has been locked into WoW. They provided an ending to StarCraft and they left very few, if any, loose ends in Diablo. They've rereleased StarCraft, Warcraft III, and WoW Classic with updated graphics. Their options for story are to look to the past. They dusted off StarCraft: Ghost and instead of making it a unique style of gameplay, which it was originally announced, they adapted the story and gameplay for StarCraft II to sell it as a trio of microtransactions. Their only new IP has been Overwatch and that really hasn't been going anywhere.
I'm just waiting for them to dust off Lost Vikings or Rock and Rock Racing in order to see the hot mess they create.
Blizzard's stuck in the past and not looking to the future. StarCraft II failed to attract the same level of eSport attention as StarCraft. Hereos of the Storm failed to effectively capitalize on LoL/DotA2. They're stuck looking at the what could have been and keep trying to take back what they thought should have been theirs. That's exactly what this message on copyright is telling us.
