No, the previous poster wrote: Men will pursue women wherever they are. So if you have women on your platform, the experience for men can be horrible, they will still come to your platform.
Are they suckers? Probably. Do the platform owner care? Nope.
The platform owners clearly care about user experiences because they tweak stuff all the time. I don't think most men are suckers. Even a real sucker will stop paying if they are not getting any benefit from paying. If you put all this together, the most reasonable thing a dating app could do to make money is actually try to provide good experiences. Of course, these days, it may be a bit much to assume that the management of any company actually cares more about making money than their pet causes.
That is also possible. But since most women don't pay, the ultimate objective would be to get more women on to improve the experience of the actual customers.
