I find no need to pirate software using linux, everything I need is available for free. Pirated software that goes un-updated is a huge security issue anyway.

So around many universities around the globe, specially in poorer countries and see how many care about those security issues.

Or many street bazaars around the globe.

pirated software with a bunch of malware in it?

It is sad, but many people don't care about it, hence why malware is so rampant.
