The thing about vacuum is that you have to make sure you still get
rid of enough heat to not cook your devices.

I know of at least one early cube-sat which did not deploy it's
antenna, because somebody didnt heat-sink the FET which should have
delivered power to melt the launch-restraints.

Never attribute to malice what can adequately be explained by incompetence.
