I'd really prefer not to give them any success metrics right now TBH. I'm not someone who was actively making microtransactions a month ago so I can't hit them in the wallet - but I am abstaining from using any of their products at least.
That's part of what I'm saying - while abstaining from D3 doesn't hurt their income it does still hurt their metrics. Every gaming company in existence tracks DAU on their products to know how much to continue to invest in it - while they might not actively care about upping D3 DAU due to the lack of any upcoming expansion they are still watching it.
