Diablo 3 has improved a lot since release.

Seasons. Themes. Give it another go if you haven’t in 5+ years.

Launch-time Diablo 3 actively felt bad to play. It had about 20 hours of fun Diablo content, and then it turned into this horrible experience that was half: inspecting the dozens of crap items in your bag looking for something someone might buy on the AH/looking for items to buy on the AH, and the other half was trying to play a "Bullet Hell" style game using click-to-move

Since then, they've completely cleaned up their act. Diablo 3 today is a lot like Diablo 2 in that you can just keep enjoying the core Diablo gameplay as long as you want

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.

D3 has no micro-transactions, though.

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.

That would require giving money to Blizzard, which there are an increasing number of good reasons to not do.

If you think the game was a disappointment, doesn't that imply you already gave them the money? It is not a service. If you bought it 5 years ago, you don't have to pay more to play it.

But you can avoid having some information brought to light specifically because of their abuse from turning you into a DAU. If their userbase goes up as a result of this scandal it's the market responding in a manner that encourages further behavior of this sort.
