Naturally, WY is purported to be neutrally grey, but look at their track record!
A1 - Ash and the company knew the entire time what they were up against, and the company activated "Zero f**ks" Mode about the crew for the sake of bringing it back alive. Long live crew expendable protocols!
A2 - The company (Technically Van Luen and Co.)denies complete knowledge of the events of A1, suggesting they're either exploiting Rip's hypersleep or are just fish on a bigger executive chain. Regardless, Burke essentially kills an entire colony to learn what he already knew for the chance to enhance WY's Bioweapon division, and he died because his greed and curiosity.
A3 - The company's sick of Ripley's shit & basically says "Hey! we want your internal hugsy buddy, rip! can we have it now?". They get THAT desperate, their digging for molten DNA samples out of a frigging furnace! Dedication or Desperation?
A:R - WY's research passed on to space chucky's (Brad Dourif) research team that have progressed further than WY ever hoped to achieve, eventually showing us that Darwin was one smart cookie, and WY couldn't of dropped out as a better time. Life Expectancy increases tenfold.
As you can see, WY just don't care what happens; as long as they get the moolah found somewhere in the xeno's sticky acidic filled veins, they'd gladly sacrifice Elvis to quadruple the profits through genetic manipulation. Think of it as Jurassic World's genetic hybrid; they didn't realise they would f**k up so bad without the information. WY have TONS of information and a dead Colonial squad; Pretty sure that's reason AND EVIDENCE enough to leave everything as it is.
They have the money. They have the technology. They have the power. GIVE US THE GODDAMN GORILLA ALIEN!
