The left doesn't care.
Despite studies by reputable firms showing over and over that Google's algorithm consistently, repeatedly and predictably shows returns with liberal favor there are those that attempt to marginalize those studies. Zuckerburg is a piece of dogshit but at least he was honest when he stated at least 97% of the entire tech industry leaders are liberal. As stated in the video, 88 top executives of Google gave money to Hillary's campaign after the primaries. Yet not one - zero - gave money to Trumps campaign. It is ignorance by choice to say there is not a problem.
If Google is selling "objective reporting" and a complete lack of bias in their search results, then it seems like a class action law suit is the proper response. Obviously, they're not living up to such a promise. I don't know if this is the case or not - it should be for a court to decide - but if it is, then a lawsuit is the proper response.
But of course this issue has nothing to do with truth in advertising or holding a software company to their license agreement. It's transparently, and obviously, political retribution. Tech companies are openly defying Trump's political ambitions and working against him. Trump and his supporters want to use the power of government to prevent them from doing this.
This kind of situation is exactly why the First Amendment was written - and why it was written first.
