There's a news story about such a company where they basically throw the bodies in a chest freezer, or stuffed many of them together in one unit, etc. Nightmare fuel...
I have doubts that such a company could keep the power on for the next 200 years, with an increasingly unstable planet (climatically and politically).
Maybe sending your body in a lead coffin into the coldness of space is a better preservation method, maybe that's why the loser billionaires are so interested in going to space..
