Josef,
If people are sure Kohs won't deliver as he has in the past, then certainly they should go for the lawsuit.
On the other hand, he's delivered in the past under the same circumstances, lawsuit threats and doubt for 20 years. Lawsuits would torpedo the project with certain loss to investors and including demise of the project. Ask Butch. He rode it out last time with a lot of heartburn but eventually got a Challenger.
The merry-go-round will stop at some point. But after being told it would stop for the past 20 years, why would I necessarily believe it will stop right now without some uniquely new information from his doubters or uniquely new practices from Kohs himself? That is what I am looking for but have not seen anything new here that hasn't happened almost exactly the same in the past. So far, all I've seen is Kohs doing what Kohs does on Kohs time.
