There exist also competitors not funded by YC, like me. I won't be on any of the lists because I'm not courting agents, I'm courting humans.

For me OSS is a weapon to be wielded. By making perfect software that cannot be improved upon, and making known my ownership of it, I'm am defending "embrace extend extinguish" attacks that would otherwise be damaging to me. Those attacks rely on being to undercut a product's position in the market with a similarly positioned product that can be just slightly better and/or cheaper.
