Same as it ever was. You see the same kind of thing is the food industry, pharmaceutical industry, tobacco industry, fossil fuel industry, etc. On the one hand it's almost inevitable. Who (outside of the government) is going to care enough about the results of stuff like this to fund it if not the industry affected? You also often need the industry's help if you're doing anything that involves large sample sizes or some kind of mass production.

On the other hand it puts a big fat question mark over any policy-affecting findings since there's an incentive not to piss off the donors/helpers.
