IIRC the problem there is that it potentially makes you liable to be sued by the company for disclosing negative/private information. But they can’t exactly hold you liable if you’re dead, so if you’re dead you may as well speak what you know from beyond the grave.

Absolutely. I was gonna edit my comment to include that but you beat me to the punch.

While it won’t help you getting suicided, setting up a deadman’s switch on the cloud that will release your testimony is definitely worth doing.
