Absolutely this. They have been cashing in on their reputation and captive audience for years. Diablo Immortal (aka Diablo Immoral), the hatchet job they did with Overwatch, the terrible state of Diablo 3 on launch, constantly releasing games before they're ready, and cash grab that was warcraft 3 reforged.

Everything is designed to squeeze blood out of the stone that is their aging playerbase. Anyone who pre-orders or even joins the beta on this game knows what they're getting into.
