I have no horse in this race. I do have experience with Trifecta and knew a lot of other happy customers. They do not claim to be entirely invisible, the flash count goes up a tick with each flash, but GM cannot see the changes (only sees 'stock' settings). That's the transparency part. They don't have a way of proving you were running anything other than stock settings. In this case it's up to the conscience of the owner to determine if they should be paying for the fix because the tune messed up the car. As has been discussed several times (from what I could tell in a search) the odds of a well tuned car failing as a result of the tune is low. But tuning does technically void the warranty and I can't say I blame GM for their policy.
