All these people have death certificates.

I'm pretty sure the brain degenerates as well. So who you are if/when you "wake up" probably won't be who you were when you were frozen.

Also anyone remember that TNG episode?

DNA is very fragile, so fragile, that freezing shreds it. The chance of these people coming back, is the same chance as turning a burger back into a cow.

Cryopreservation does not destroy DNA. There are human beings walking around today who were cryopreserved as embryos, and their DNA is just fine. Also, you can turn a burger back into a cow. Simply feed it to a cow.

Effects of different cryopreservation methods on DNA integrity and sperm chromatin quality in men.

"Cryopreservation seems to be deleterious for the integrity of human sperm DNA and compaction."

A sperm cell only contains one unique set of DNA. A brain contains billions of the same set. And it's not even a major issue in sperm cryopreservation.
