Cool, what we really want to do is inspire people to turn on their computer, download BOINC, find some project that they care about and start helping humanity by processing science.
Of course price support is valuable too, and if people want to throw up commercial projects then that's feasible and the Gridcoin team I believe would support it as long as its not ethically dubious; to be rewarded a project must be voted onto the whitelist, that vote occurs on the Gridcoin block-chain for full transparency.
I agree Sia has some problems there too, the only project using contracts that I have seen addressing the problems of regulatory compliance is Dharma.
The nice thing about Gridcoin is that Gridcoin itself rewards the people doing the work, no contract exists between the work requestor and the person processing it; so I think we don't have that legal issue.
Unfortunately I'm on the move all the time so my main computer is a chromebook, I don't have the power or capacity to process much outside of browsing!
