Pretty much any software or games. Not really for moral reasons especially, but I mostly run Linux so most of them aren't available anyway, and if I do get something it's usually such a pain in the ass to actually get it working (and keep it working whenever there's an update) that it's usually not worth it when there's often a FOSS alternative. Also no pirating indie games.
Books, with a few exceptions. I don't want to screw over authors so I don't download books, but there have been a couple of old ones where the author is long dead and I already paid for a paper copy, so I snagged the eBook just for convenience. I figure that's not hurting anyone except the publishing company so whatever.

Also with games I'm one of those extremely patient people who can wait years for something to go on sale, so what I usually do is set a price in my head for what I think something's worth, and then ignore it until it ends up at that price. So like: Baldur's Gate 3 - they did a good job and released a proper working game = full price. Cyberpunk - looks alright but it was a big mess on release and had a bunch of stuff missing = wait until it's all fixed and has all the add-ons in a bundle, $25. Last Of Us PC = it's one of my favourite games but it's 10+ years old now and was also a bit of a mess on release so they can fuck off with the $70 price tag = $10 tops. No Man's Sky - Might be decent now but they really bullshitted that one on release = wait until it shows up for free on Epic or PSPlus. And so on. There's a lot of them lol.
