In my area, single people also use Hinge, Bumble, CoffeeMeetsBagel, OKCupid, POF, Match... I'm fugly as hell but even I was able to find someone on a non-Tinder platform.
I don't think the author is claiming to be banned from every dating app, and I don't think Match Group connects the profiles of users across its owned platforms, so it's not really relevant that Tinder is owned by Match Group for the purposes of what happened to the author.
Did you read my last line? I did not suggest they do so now, but I do genuinely wonder how long until they do. It's a big issue that they have been allowed to control this market the way they do. It's somewhat tolerable today because they've avoided taking steps to call nsolidate them
. But also only for that reason.
