That reasoning defies common sense. You're suggesting piracy occurs because the software industry doesn't support out-of-date software?
That's a deliberate case of planned obselence.
And people in the software industry can't fathom why people pirate software.
Most piracy targets the latest software, because that's where the demand is. Not antiquated, unsupported versions. (The one exception is Windows ME in China.)
You'd be surprised. The majority of software pirates deliberately pirate simply for the sake of free software yes but, there are times when I've had to get fixes/cracks for games that I physically own both disc and serial key in perfect condition, that I literally just bought at the store because some "Gold Edition" was bugged right out of the box and the game company was less than supportive.
Just a couple examples off the top of my head:
Neverwinter Nights 2 Gold Edition: Released a year or more after NWN2 and...the first quest was bugged and impassable. Atari...who woulda thunk?
X2 Reunion: Physical discs missing necessary files to play the game
I had to get fixes for these from third party sites definitely not supported by the developer because...the developers were definitely not supporting their customers.
They eventually pulled their heads out of their rears but the whole process was like pulling teeth.
I've had an infinite amount of troubles due to game discs and serial keys and registration servers.
It's not always the developers that are to blame though. I've been to retail shops carrying games that were no longer supported such as the original All Points Bulletin (not APB: Reloaded). The original game box is less functional than a paperweight. The game and servers are both discontinued so once you install the game...you can't update it and you can't play it (it's an online only game). You literally can't do anything with it. I think I was at a Gamestop and I told the clerks hey, you're selling a 30 dollar drink coaster and they wouldn't even take it off the shelf!
I've got computer games from the 1980s, 1990s, etc. that still work fine albeit the older ones need DosBox or something to run.
I've got much newer games that are unplayable because developers decided to tie their registration to online servers and then once they got X amount of dollars out of their customers, stopped giving a crap about both the game/software and customers.
My only point is people want to be assured that when they purchase a piece of software that they truly own it and that they don't have to rely on some company's whim to stop allowing customers to use online registration.
The major problem with these intrusive and restrictive DRM and registration type systems is they don't punish the pirates. It's been proven time after time the people they really punish is the actual paying customers.
