Perhaps not. But you could still imagine a for-profit matchmaking service that would do a better job of aligning its interests with those of its clients. For example, it could collect only a small fee upfront with an agreement that if you meet Mr. or Ms. Right you'll release a larger fee held in escrow.
I imagine that would need to be quite personalized and high touch, but it would be an appealing contrast to standard dating sites, which have interests diametrically opposed to those of their users: a user who makes a long-term match will stop paying the membership fee, so the site owner has no real incentive to help the user do anything but churn.
I mean, if I had the time, I would create a non-profit to do so.
And yes, there are probably small mom-and-pop types of businesses that just want to keep their status quo.
I believe I've heard a few years ago, that at least one country operates a dating service for their citizens. I can't find it now, but apparently the Tokyo Metropolitan Government just launched their own dating app, "TOKYO Enmusubi"
