You also pay for goods or services 'only' because it is required by the seller, not because you like it But seriously, software is tricky business, it's very difficult to measure the 'added value', or justification as you put it. I know we established analogies suck, but think about this way. Imagine public transportation. You have the option of buying a ticket or walk. Instead, you just jump over guardrails, claiming you only want to 'test' the system and that you will buy a ticket at the end destination if you like it, or claim that if could not get in without a ticket, you would have not used the system anyway. The transport company has the same costs regardless if they have 1 or 100 passengers per carriage, so you might think it doesn't matter. Now, for those that DO buy a ticket, what you are asking is, why is it bad if you buy a ticket and then let in 99 of your buddies in for free ? Because at 1 customer per ride, the system is not profitable. If none of your buddies would have paid anyway, the system is doomed as it's not sustainable at that ticket price. If some would have paid, but didn't, the system is also doomed, as they lost revenue. Only paying customers make THIS particular business model viable. Alternatively, they could turn to subscription, or, the easy way, just tax everybody (not really a win, eh ?). That's why many systems have complex admission systems and/or people checking passenger tickets occasionally - they are the transport company's equivalent DRM. Does the guy who checks your ticket bother you ? He could penalize you - you might have bought a proper ticket and misplaced it. Paranoid companies might employ hidden X-Ray machines to check on you. Your actions while using the system might be supervised via camers. But the bottom line is the same - whether you are bothered by tickets or not, your choice is to USE or NOT USE the transport system. You can protest in front of the company about terms, prices, but you DO NOT GET TO RIDE WITHOUT A TICKET WHATEVER THE 'REASON'. This also applies to copying - I hope I don't have to explain why copying tickets for your buddies is a problem ? My suggestion is to get a bicycle. Clean, free and keeps you in shape
