Felicity
Mostly public knowledge stuff. Heavily bio-engineering, on paper they look pretty clean but doesn't every evil corporation? Underground has a lot of conspiracy chatter. They didn't start looking to recruit refugees until baby Osborn took over so they haven't been mining the multiverse for research like Stark.
But that could have to do with the fact that the refugees from alterverse avengers have a massive hate boner for Norman Osborn. They seem to shut down too much of the talk on the public side of the network but stuff sneaks out and looks like at the very least alternate Osborn is into some fucked up shit. Which means Oscorp is probably into some fucked up shit here too given how similar their worlds are.
