Pathfinder 2E Why No Big 3PP Support for PF2?

[Retreater]

I see that Frog God Games for example does most things in 5e, Pathfinder 1e, and Swords & Wizardry versions now.

It looks like they're making motions to go with Tales of the Valiant (to replace 5e) and OSE (to replace Swords & Wizardry).
FGG are no fans of PF2 - and will likely be dropping PF1 soon.

We tried to support it early on.

I had asked on the FGG Discord a while back (before the OGL debacle) and they said they had little to no requests for PF2 material

Legendary Games is one of the bigger 3pp companies that includes regular PF2e content now. They usually do their big monster books in three versions, 5e, PF2e, and PF1e now.

At least on a cursory look (I own a couple) they're well done for 2e, too.
