There's a decent counterargument - take it or leave it - that this kind of research is extremely difficult and expensive, and upon success, privately weaponizing it and/or selling it to organized crime or nation state-level actors is extremely attractive, and therefore, the ability to short the stock of a sloppy/insufficiently-careful HW vendor to fully or partially fund the research instead is legitimate in that it ultimately improves overall-societal welfare relative to those other alternatives.

Vendors who wish to discourage that behavior could offer comparably-large bug bounties instead. And, of course, make their products more secure in the first place.
