An organization, or company that is known to use dirty tactics to make even more profit then their already ridiculous figures. Some of these tactics can be seen as evil, or simply dirty. It is not to be confused with illegal, as these organizations will make sure that what they do is legal, but just "micro" "soft" to customers.
One common tactic is to price gouge, or hide clauses to make customers pay more after they've already paid. This is very common with software licensing companies.
I already paid 10k for this software, but now they want me to pay another 1k per computer just so the client portion can work? That's so microsoftish!
