They have actually become less politically activist with their money. Of the 9 families in previous election cycles

Zuck - wanted to run for President as a Democrat

Laurene Powell - huge left wing donor

Google Founders - huge left wing donors

Eric Schmidt - led digital for Clinton, huge Obama backer

Ellison is the only right wing one of the group, the rest have just stepped back from politics, spending less (except Laurene)

Not to mention those just below the cutoff like Dustin Moskovitz.
