My biggest peeve is that the monopolist Match Group (runs Tinder, bought and ruined OkCupid, etc) and its nearest competitor Bumble have both adopted a card stack system that makes searching impossible. They also won't display any statistics to a user about the number of people who saw their profile - keeping their customer in perfect darkness.
In most fields of life, a customer would not be satisfied with this kind of shit. A company advertising their product would demand instant feedback about the number and profile of people who viewed their ad, where they came from, how long they browsed, etc.
Basically, we are all getting scammed by a few monopolists, who are actively ruining people's ability to find partners. I would support a politician who promises to let the best university in the country to build a non-profit dating site.
