There is a viable viewpoint from Roberts and Wanderports standpoint that could be:
We aren't diluting or asking Joe Schmo public to pay for this potential invention to this point, so take a hike and stop bugging us. Your choice to buy the stock or not, but we aren't taking a dime from anyone, so ---- off.
That sounds very plausible and makes the most sense and is actually fair if that is their viewpoint, who knows. If they aren't taking your money, they don't owe anyone squat. Thought I'd throw that in there, cause it makes sense to me even though many, including myself, are frustrated over the months and yrs.
