This conversation went sideways a bit and then petered out over the weekend while I was sick. I wanted to throw some suggestions in.
Easy suggestion:
Form another 501 C 3, "Wikipedia Foundation" (WPF) or somesuch. Transfer it the trademark and ownership for the domain name. Have it license those back to the Wikimedia Foundation for a notional $1/yr.
Have it have a minimal, trusted board, with no WMF overlap, and charter to protect those assets.
It's safe; it's not actually doing anything, so it can't be sued. If the WMF gets sued into oblivion, the domain and trademark don't go with it, and the WPF can then license the assets to whichever appropriate new free content organization springs up in the wake of the debacle.
Alternately:
Spin Wikipedia off into a Wikipedia Foundation, taking the lawsuit risks with it, and licensing the domain and trademark from WMF. This allows the WMF to broaden its horizons a bit and become a long term umbrella trust for open content in all its myriad forms, spawning new project foundations as appropriate.
This might be easiest. Among other things, a spun-off WPF could even be a not-for-profit company, not even having to be a 501 C 3 (with all the years of paperwork and IRS foo-foo); I doubt that anyone would seriously object if a not-for-profit WPF running the Wikipedias was funded in part by donations from the 501 C 3 WMF, or that donations to the WMF were partly directed on to a not-for-profit.
I don't believe there's anything illegal or unethical or fattening about that. You just need to fully disclose any relationships to donors and make sure that the not-for-profit Wikipedia Foundation books are sufficiently open, and not being used as a tax dodge.
This all needs an appropriate corporate attorney review, probably corporate attorney with tax and nonprofits experience.
