Linux software is not cheap ....

Software installed in Linux has never been paid before (except for commercial Linux operating systems and large databases ). Today, I installed helix, so I couldn't help sweating. I didn't expect the software under Linux to be as expensive and scary. What's even more sweaty is the cracked version, pirated serial numbers, and so on, although eventually pirated. However, I still feel a little hard to tell. First, I corrected my incorrect opinion. Second, I learned one thing. There may be free lunch in the world, but free lunch may also be stolen. Whether you eat well or not depends on your morality. Finally, Linux is open-source, but it is not free of charge.
