alt Hacker NewsI 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.
Things like this can actually be a good way to nudge a company in the right direction sometimes. Nobody uses those internal review systems, and sometimes their stats are actually important. A handful of users might make up a really big chunk of the reviews.
In a similar vein, I once met a woman who told me how she would enter every single one of those stupid contests that you'd see printed on cereal boxes and ice cream containers because literally five people enter into those things, so you're odds of winning are surprisingly high. Apparently she won a bunch of them, but her favorite was when got a week long vacation that included going on a fishing trip with Ben and Jerry of "Ben and Jerry's".
