While a union that represents workers interests is a good thing, I think it would be dangerous to give even a part of google to people with ideological fervor. If, for instance, this group actually wants to and succeeds in turning google into a tool of the cancel culture, things will get ugly soon.
Now that leaves me wondering if it is wise to leave this comment here...
edit:
Just an example from the mission statement:
> We will prioritize the needs of the worst off. Neutrality never helps the victim.
What this means is, not all google workers will be treated equally by this union. "Victims", i.e., persons will be ordered by their "oppression status" and gain preferential treatment. Now it will probably be fun to watch the details in this valuation process (e.g., "is a woman more victim than a black (disabled) male?"), but this inherent categorization of human beings into more and less worth is ugly as hell.
