Those other industries you mention have each been subjected to relatively large amounts of regulation over their history, some have been targeted for antitrust in the past. By comparison the "tech" industry has been subjected to very little regulation in the US, almost none. We have seen these "concerns" from other commenters in the past -- "it is not fair to keep picking on X" or "everybody else is doing it" -- but it just comes across as being from people working within or dependent on the industry. Why would anyone else be sympathetic to these concerns?
