For researchers, in all honestly that is a very, very good reason to go GPL. If someone wants to profit off of it, it's not that they can't use the code commercially, they are just forced to hire you or pay you to dual-license it.
There's no reason why a company whose stock goes up $10B due to your model can't cut you a few million of that.

In March 2002, Affero, Inc. published the original Affero General Public License (AGPLv1) for use with the Affero project and made the new license available for use by other software-as-a-service developers.
