I think that, if you believe the FAANGs are dominant enough to be considered infrastructure, you can make a case that their putative political bias is worse that other company's lobbying. At least lobbying results in the introduction of bills that can be debated in a legislature with public input (via calling your representatives, as well as protests and counter-lobbying from other interest groups). The FAANGs' decisions on how to regulate their platforms are subject to no vote or other public input before enactment.
