Tinder's biggest problem, IMO, has always been whether it's a dating app or a hook-up app. I've found that generally, men consider it a hook-up app, while women think it's a dating app. Granted, there's been absolutely zero rigorous study on my part, so my conclusion is easily 100% confirmation bias. However, I think it's worth noting that generally, women are already less likely to use a dating app than men, and would be even LESS likely to use a hook-up app than men.
I would bet money that if the $500/month sub added some fancy symbol to your profile so everyone knew you were paying $500/month, you would easily get more matches simply because it shows that you have money.
Only if you let it be. You have a market of people who want something they know is naturally difficult. So they'll struggle to recognize if you start making it more difficult to obtain (because they already expect dating to be hard).
So you can make things more difficult for users (reducing the number of "successful customers") then ask for more money to make it less difficult.
The only risk is that if a competitor makes it too easy, people will leave your platform... but that's why Match Group exists. They buy any large enough competing platform and ensure that the average difficulty across all their owned platforms is fairly consistent.
Feels like Twitter is about to get into the pimping business.
If so, something is deeply wrong, and it's not something hookup apps can solve.
Paying for Tinder, in its various tiers, lets you swipe on an unlimited number of people in a day, or, for more money, lets you just see who swiped on you as soon as they swipe "like."
I don't pay for it personally, but if you are paying for it you're saving time and reducing a lot of the (Tinder imposed) friction, so, I get that. I also get why some people might not see the value in Tinder in the first place, but it does make meeting people in a romantic context a lot easier, or at least more streamlined.
Also as you say its in Tinder's interest to put everyone who swiped on you into a different queue and throttle the hell out of it. Drip feed matches into the stream of 'no's. As that liked queue gets bigger, your rejections grow and therefore your desperation/ willingness to pay rises. They can literally see who is already a yes and could prioritise those if they were pro-user. They do the opposite.
I've also noticed they will use this queue of people who liked you strategically. If you haven't been on in a while they will release some matches to build that reward expectation back up and then turn it down once you're doing what they want and engaging daily. (I can't prove this but it feels like the best way to get some matches is to wait for their 'we missed you' spam)
