The honestly of clients, even businesses, is...questionable. I have an acquaintance who sells a very expensive software suite that is absolutely needed in a particular industry. Price for a perpetual license is 6 digits.
The big boys in the industry won't risk problems, and anyway, that's a small price for them. However, the many smaller companies? They may absolutely need the software, but that's a substantial price for them. If they can get a cracked version online, they do.
And the cracked versions? They are made by companies out of legal reach: Russia, Belarus, Pakistan, India. They crack the software, and either put it online for free, or even have the cheek to sell it for a reduced price.
I've told my friend/acquaintance that he really needs to put the software in the cloud, accessible only via browser. However, this would be a massive undertaking, so he hasn't done it (yet).
