I feel you. From my side I try to complain / rate / review every time, even if it's a low effort action, to cost them time and in the case of the regulated companies, to slightly worsen their complaint stats.

There's enough of users to start making a difference. Really, even a low effort action raising valid concerns (security theater, a lie, google's monopolistic position, anti-competitive, etc), keywords that will make their response more careful and potential complaint to the regulator more impactful.
