In both the 2016, and 2020 elections, these pages reported research that Google was biasing search to favor the D nominee. And I was present at a TGIF (attended by a substantial % of G workers) in 2015 when a director bragged about changing the election results in a Central American country.
It takes a "Some animals are more equal than others" kind of brazenness to claim that concerns of Republicans that they are getting unequal treatment regarding these filters.
Without reading the details of the proposed bill (something which usually takes a JD & access to the Federal Register to decode anyway), the description sounds like they are wanting to require that campaign-related email requires an opt-out. An ugly, transparently self-serving bill? Certainly. But G in particular has no valid claim of neutrality, so these untraceable in-kind donations must be stopped if there is to be any hope of free and fair elections.
The question that I have is: will the opt out actually work? I've got one company whose emails come through no matter how many filters I try to slap on it. (And yes, I only use gmail for work.)
