If you're talking about Bowser, the only thing they convicted him of is "conspiracy" to do things that shouldn't be illegal [1]. All the other charges were dropped. If you think "conspiring" to sell modchips is a crime worthy of prison I don't know how to convince you that we should have a fair and just legal system. It was a plea, too, and anyone who knows the legal system well understands that plea bargains are generally unjust and used to bully people into not defending themselves.
