Both options present danger, though I agree with Paizo's choice here. WOTC is left with two choices, ignore the possible copyright references in Starfinder, say, or sue them over it.I'm still curious about that, simply because Paizo's decision to try and strip the OGL from their Starfinder and Pathfinder 2E lines strikes me as being more risky than staying with the OGL v1.0a. I'm no lawyer, but given how the whole "you can't copyright game mechanics, just expressions" is untested with regards to what constitutes an expression in the context of a tabletop RPG, and that there are at this point thousands of pages of Starfinder and Pathfinder 2E material, you'd think that Paizo would be leaving themselves open to a lawsuit for potential copyright infringement if they go that way (especially if they strip the OGL out of reprints of existing books in those product lines).
Now, they also leave themselves open to such a suit if they stick with the OGL, presuming that WotC tries to say that it's "revoked/de-authorized" and that Paizo is thusly infringing on copyright anyway. But my lay read of the landscape says that Paizo is more likely to prevail if they argue that the OGL v1.0a is still valid than if they try to claim that there are no copyright infringements anywhere in Starfinder or Pathfinder 2E.
Now, that's a slight digression from what you were saying, so I'll try to bring it back around; given that Paizo is WotC's largest direct competitor in the tabletop RPG business (VTTs notwithstanding, since I agree that's what this whole fiasco is really about), I have to wonder just how long WotC will be silent and let what they likely see as potential copyright infringement on Paizo's part fly.
If they sue and lose and a court rules that broadly Paizo is good to go and that you can't copyright mechanics in the way WOTC would seek definitely, well then that's the whole thing crumbled to dust, isn't it?
If a court finds in a clear-cut way that WOTC can't claim copyright to mechanics like how they want then that also really frees up competitor VTTs to integrate 5e again.
Since WOTC seems to not really care about traditional TTRPG monetization (i.e. selling books as the primary driver of revenue), which is really Paizo's sole focus, and the downside is so large, I would probably make the same educated guess Paizo is here.
