No its not at all. There have been some really good posts about it here even. Personally, I'm currently using non pirated software professionally that I obtained initially through piracy and achieved mastery of. No way I ever could have afforded it, but now I'm indirectly promoting use through my work and am a customer.

For better arguments read Breakey or Krukowski.

If you are new here keep an open mind, there's a lot to learn and some pretty smart cats here to teach (and I'm not claiming to be one of them).
