That is what I can’t understand about such businesses, why try to rip off a company (another business) by using the free version against the terms of the license. They can legitimately claim the cost of the software as a business expense.

This is also going to reduce their tax bill, so I know who I would rather pay, avast! software or the taxman, no contest. Unless of course they are avoiding tax as well, in which case I hope they have their collar felt.
