Oh well... The last reason isn't true... Take a look at how much was
invested in Linux, OpenOffice.org, KDE, Gnome, Python, Perl, R, etc.

Return is something *very* relative. And it might even be considered
financial return since the project leaders of the above project sooner
or later got contacted to work for some company that would benefit from
their work and would pay their bills...

With this I agree. I'd start with the most common and free specs, as an
initial release and then let other people / companies add the paid
"specs" or simply say: "do you want it? if you buy the spec then we can
start with it, you'll also have to wait X days/months."

I hope some organization needs it and allows it being released as open
source. ;-)
