Unions at best enact the will of the workers and I wonder if most Google employees would prefer all this ethical drama to just stop. In that case a union would most likely have a rule banning all debates on controversial or non-work topics (on the job using google equipment). Which would lower the amount of debate rather than increase it. Unions aren't a magical solution to all problems.
