250 people risking their cushy jobs in a matter of people half-way across the globe - i think it is worthy of attention. And anyway, the extremes like visible activism is usually just a tip of the iceberg.

I don't envy Google leadership here, though they may have to partially blame themselves:

"This new internal political divide at Google sheds a spotlight on a long-standing diversity effort: designated employee resource groups (ERG) intended to celebrate employees with marginalized identities. But in today's climate, these groups may be sparking more political controversy than Google ever expected. "

I mean you start organize people around their ethnic/etc. identities, and as a result you may deepen the divides and raise the tensions. Reminds the situation of Indian caste system which was really formalized and strengthened by the British.
