In the Star Trek: Discovery Episode S01E05 Choose Your Pain we see
Michael Burnham release the tardigrade.
The tardigrade has been an integral component of the system that enabled the USS Discovery to achieve faster-than-warp speeds.
In the same episode,
Admiral Cornwell orders the Captain to share the technology enabling their travel speed, implying that the tardigrade technology is vital.
My question is:
Why is Michael allowed to release the tardigrade?
