Ok I figured it out, it's Mozilla's Facebook Container plugin. Sorry HN doesn't let me delete the comment any more. This one is not your company's fault, though I still think you should feel bad.
If I had to take a stab I'd say it's because they work for facebook. A company many people find to be unethical.
I'm aware the change of working for another company wouldn't be quite so stark in tech, but it can still be a massive boost to your career to have a big name on your resume. Most people at those companies would just be doing boring day to day things, and not plotting world takeovers.
