Cracked databases are static. They are frozen in time. If you are working on a 2021 VW Golf, a cracked 2015 version of ESI [tronic] is useless. In fact, relying on outdated software can be dangerous, leading you to splice wires based on a diagram that was revised three years prior.
This is the biggest danger. "Cracked" software is a favorite hiding spot for malware. You might think you are downloading a wiring diagram database, but you are actually installing a remote access trojan (RAT) that steals your browser passwords or encrypts your shop's PC with ransomware. The risk-to-reward ratio is terrifyingly bad.
In the hands of a pro, ESI [tronic] is the difference between a car fixed in an hour and a car parked for a week waiting for a dealer appointment.
