I don't think this solves all of it since it makes some weird assumptions. Does the developer really say "Hmmm, I want to cause an unwanted negative experience for the player" before adding lootboxes? I am pretty sure they don't, so this definition is not a very good one. OTOH, maybe just changing "to cause" to "that causes" would clean this up quite a bit by removing the assumption I disagree with, so maybe it's just in the way I read it.

Note: In my opinion, it's perfectly fine to say "this is tough to define but I can try to say 'yes' or 'no' to specific examples". It's also acceptable to me to admin (as you have to for some words) that a word doesn't have a real definition but is rather the product of confusion or convenience.
