You cheap piece of shit. You're not entitled to a discount. You're not entitled to a free upgrade. The developer is entitled to be paid for his work. Developers of free software aren't giving you your due, you fucking ingrate; they are choosing to waive what they deserve, which is their prerogative. You deserve nothing.

What have you ever produced? What have you ever provided the world besides whiny blog posts? You think because your accomplishments as a human being -- the sum total of your entire life -- are worthless, that means everyone else's is worthless, too?

Crawl back under your rock, you scum.
