Sorry dude, you have a right to your opinion -- but most of what you just said isn't true. I understand you think it's ridiculous, but being against rent extraction is a classically leftist political philosophy. You're right that it costs money to operate servers, but that doesn't mean those servers are not the property of Valve. They utilize that property to collect rent from publishers.
That fact is not well liked by leftists. By liberals? Sure, go nuts. But I think you're in the process of finding yourself in the latter camp, at the moment. I'd definitely encourage you to look up leftists vs liberals because I think you may have a misunderstanding.
Regardless, I agree the hate/vitriol can go overboard coming from these types of people. I agree with the political and philosophical underpinnings of their frustration, but we are all born into a rat race and taught that we should do anything to get out of it, so no one actually thinks about whether things like "passive income" are right or wrong. We are taught that's what you gotta shoot for, and I'm not going to blame someone for still believing that.
