Pollen-Free Corn

Another way of thinking about corn like this is sterile. No pollen means no seed corn; hope you like buying seed every year, because your going to have to. Most vegetable seeds are sterile nowadays anyway.
But the bee's are going to be pissed.

This sounds like what is referrred to in agriculture circles as terminator technology. The goal is to render it impossible for farmers to retain a portion of their crop to provide seed for next year. The farmer must annually return to the original seed producer.

It simply helps make farmers slaves on their own land.

It obviously needs pollen from somewhere, otherwise no seed. Probably initially pollinated in some remote research field to acquire desirable trait, then when farmer buys it he plants it alongside un-modified hybrid for pollination. If you planted a field of only this modified seed, you would get nothing.

The link indicates that this specialized corn is intended
to be used to produce an engineered ' theraputic` protein.
While I agree with the forgoing comments about the economics
of sterile seed, I must agree more with the initiative to strictly control
any release of living, reproducing, form producing artificial agents.
The article states "We know so much about corn.." but
I doubt we know enough biology to turn such things loose just yet.
