You see it all the time because there is truth in it.
There is also truth in the statement that you can get a fanbase here.
This is by far the most entitled and stupidest shit I've read here on this site. It's the same as thinking you can pay artists with exposure. Or that interns don't need to be paid because they should be happy to get "work experience" so they can later get a job. It's the same dumb logic.
Even you should realize that the statement is simply wrong. The most valuable person in for devs will be family, friends, etc.. It's incredible how important you think you are. Second of all, for their business, paying customers are important. Not some pirates who enjoy your content and don't pay. You think by playing it, jerking off to it and writing in a forum you create hype which will make the dev rich. That's absurd. Listen to yourself.
Further more: most people who pirate games won't support it. How many games have you downloaded and enjoyed? How many do you support? And how many backwards "reasons" did you come up with after enjoying a game to justify not supporting it?
A good example is Word of Goo. 90% of people who played it pirated it and only a "very small percentage" of these bought it afterwards:
