This claim is factually false. Cyronics organizations don't use their customers' bodies for research, and in general they don't do much research of any kind.
You have clearly never read the Alcor case reports. Whether you view them with horror-at-the-ineptitude, or awe-at-the-learning-process, they're clearly having all sorts of fun experimenting with the bodies.
Of course, whether this is useful research is up to you to decide, but it's clear that the "preservation" side is still rather experimental. They do at least document all of it, too.
That's clearly anything but scientific research.
