Speaking of which, your OP is extremely misleading in that you 1) have omitted most Americans, of all parties, want more filtering of false information and 2) that its a combination of government and tech companies that Dems support filtering out false info more than Republicans. The lead of the story is:
Moreover, you are not asking the important question: why?
The reason is obvious to me, and that is that there has been a concerted effort by a combination of groups to mislead the American people in a manner that has, for the time being, been more at the expense of progressive causes than conservative ones. And it has had consequences.
Note the rise of people like MTG to positions of power, largely premised on National Enquirer-level research she has read on line about her pet peeves. This is a frequent issue for the extreme right in this country, and an echo chamber founded on clicks feeds it for financial gain.
Or, look at the concerted, organized effort of Russia or other foreign disinformation peddlers who have attempted, with varying degrees of success, to influence US elections.
Note I said "for the time being." That is because right now the amount of distortion and false information being promoted that attacks the Dems and the left in this country is much higher than the Republicans and conservatives. As discussed many times that has to do with the shifting demographics in the country and the resentment class which is ripe for the picking by those who make money appealing to that resentment.
