Articles like this always push me towards the Stallman way of thinking that all software should be open source and everyone should have the right to modify/fix/change the software in any way they see fit as long as they aren't trying to resell it as their own work. It's a tough subject, I make an extraordinarily good living from writing closed source software but I constantly feel as though I should support open source software more.
