Because these details might be what matters or not when it comes to receiving rewards for reporting them. And these things you listed are different things.
I can just speculate the reasons and agree with you that there should be rewards for reporting other things. Or maybe that’s a ktos luxury we don’t have or didn’t have in the past (since this is a recent example).
And as much as I hate it, this ktos article pretty much discloses that it wasn’t illegal to have alt accounts to Diamond Anvil your weapon in these events. My opinion about the whole thing isn’t great, you know, but I still gotta try to see what things really are instead of blindly judging, be they good to read or not.
EDIT:
Also, it’s not that companies/etc will be 100% transparent all of the time. The thing is that in some cases such claims would make sense and in others they wouldn’t - either way you’d have a good explanation or concrete proof instead of a random rant thinking you’re right and that’s it.
