I have always kept everything airgapped, the best security is isolation.
I download stuff to a tablet, with nothing of value or interest on it, dump it to the sd card, then move it to the offline systems with a USB card reader.
Even my servers (mostly ARM SBCs with one RISC-V) were set up to work over a wired offline network.
Also most of my pirated stuff is things I own that I yarred for the crack if it was more convenient than cracking it myself.
