Just skimming the regulations, I don't believe that it would qualify as a 501(c)3 as they don't receive "broad public support" [1] whereas the criteria for a 501(c)6 match exactly with their goals. Additionally the (c)6 allows for political activity related to the purpose of the organization, which seems like a good ability given the current intersection of politics, regulation, and tech. [2]

I'm not sure what you mean by "incentives". Perhaps you could elaborate.
