about 20 years ago. Early 2000s I started messing around with Redhat and was suprised that a full OS that did most of the windows things was available for free. when Ubuntu gained traction I jumped on that and tried distro hopping a bit before landing aolidly on Debian derivatives as my linux of choice. I remember catching a ban in WoW because WINE was detected by their anti cheat for a while.
First I would get myself paid. Then I would drop a big rock on DC and credit reporting companies. Probably take out a bunch of healthcare insurance companies. Spend a few hours looking up companies responsible for the most pollution/human rights violations and remove them. Drop a big rock on the Kremlin and CCCP headquarters, probably North Korea too. Lots of big rocks dropped from really high.
