Your conclusion begs the question that the corporation in question is tyrannical or disdains privacy. Apart from that, I'll absolutely own that I want to see them succeed; I believe in the likelihood that big-data analysis is a valuable tool in conquering the diseases that have been resistant to past methods of devising cures. I volunteered my DNA for this purpose (and none of the DNA that 23andme holds wasn't volunteered for this purpose).
I don't seek an answer, because I believe the question is answered that 23andme is not tyrannical and doesn't disdain privacy. Neither does Google, for that matter, and I think many people agree with such an assessment (Gmail has nearly half a billion active users).
"Begs the question" means your argument presupposed the truth of this part of the statement instead of supporting it.
