So, you don't want to give "Microsoft", the big company, money for their office suite. It's too expensive. Tell me, when you pirate it, how are you giving back to the engineers that get paid to code the program? When you pirate Photoshop, how are you supporting the secretary that arranges the lunch and learn sessions the engineers are going to, to learn new skills and get ideas for new tools? You're not.
I bet you'd agree numbers can be stolen if the numbers were coming out of your bank account. You don't mind if I take those numbers, right? They're just numbers... They can't be stolen.
Are you ok with someone using your car for a long trip when you're not using it, as long as they provide gas?
And tell me, how exactly are you "providing materials" when you take someone's program (without paying for it) and run it?
