Did you respond by asking them how Reddit makes money?
The anti-corporate mentality isn't new, but it does surface in different ways and communities over time. The Reddit hivemind leans very anti-corporate, albeit with a huge blind spot for corporations they actually like (Reddit itself, their chosen phone brand, the corporations that produce the shows they watch).
The Reddit style rebellion is largely symbolic, with a lot of shaming and snark, but it usually stops when it would require people to alter their own behavior. That's why you got dog-piled for doing something productive on a site where user-generated content is the money maker.
