It's more anti-military / anti-imperialism than anti-corporate. Yes, the bad guys are a corporation, but I get the feeling that they did that to make the film more marketable. Americans probably would have a much harder time cheering for the aliens who are slaughtering US Marines. But very little about plot would have changed had the bad guys been military instead of a private corporation.
As for anti-technology, I think it's more about the dangers of abusing power of any kind, including the power that technology lends us.
