Potential problems:
- Launching a dating app from scratch; where do you get your first users if you're ethical and refuse to fake users? (If you're not ethical, people could just use existing unethical dating sites with fake users.)
- Keeping the business from being bought out by Match.com and enshittified, just like its predecessors
- Developing a business model that doesn't incentivize unethical behavior, as OkCupid famously pointed out before it was bought out: https://gwern.net/doc/psychology/okcupid/whyyoushouldneverpa...
I'm probably posting on the wrong forum, but I don't think VC-backed startups can solve this problem. You need maybe a worker-owned co-op, or an open source non-profit like Mastodon, to have any hope of resisting the pressures of capitalism that ultimately ruin all these sites.
