Because once they get involved they're often not worth picking up.
I think there's a lot of stuff out there that would provide value to both parties if they could simply connect. Something like Gumtree or Craigslist is an attempt to capitalise on this.
e.g. I have a broken machine. It'll be useful to someone for spare parts, to fix and resell (or for fun), as a placeholder (since it sort of works) until they get something better. I'd probably give it away. But dealing with all the time wasters on such platforms makes me want to just toss it.
It's similar for some ideas where there is definitely profit to be had, but simply connecting with the customer, convincing them that it will help them, convincing them you're actually honest, etc etc, all costs more than it's worth.
