I didn't design that system, and I think it is this way because in the past without forensic evidence, the witness role basically put the burden to people who are testifying or on the stand for questions. That's why nowadays when the suits wants to push shady things they go off record cause they don't want to keep any evidence. It's up to the minions to smart up to make sure you cover your own ass.

And, sometimes company make or break during trials. I don't want to see value flop, but I also think 30% is a lot if you don't even use steam features. (here I mean you only publish on steam, but you don't use their DRM/Friend/Matchmaking, workshop, lobby, etc. But if a dev do indeed use those backend service I think it's justified. )
