I would imagine that most companies operating a loot box model will be evaluating their strategy going forward to see the options that are available rather than simply disclosing the odds.
Companies have responsibilities to investors and so taking any action that could potentially hurt sales would never be welcomed.
If CG disclosed tomorrow that the odds of 330 shards dropping on a single purchase was 100,000 to 1 for example, this may not put off players who typically max out characters but it would likely put off players who buying a couple of packs on the off-chance.
