They drain because of computer flash-memory, clocks, radio presets, electronic rust preventers,etc. The OBII and newer computer system seems to be biggest "key off" battery drain.
I'm a little new to cars and trucks built after 1995. I did not want to own anything with an OBD-II computer system - but finally had to give in.
I've got an 95 Subaru Impreza, 99 Kia Sportage, 2002 Subaru, and 1999 Dodge Grand Caravan that all have OBII. All will drain the battery to a point it won't start in 4-6 weeks if not started at all. All my vehicles without have no such problem.
My 99 Dodge owner's manual cleary states the battery will discharge if not started at least once a month. It says to pull certain fuses for long term parking.
My original "fix" was to install battery disconnects. That works fine - but that caused me problems with NY motor-vehicle inspection. I finally installed the maintainers and it was the best fix for me.
Somebody that does not have mulitple vehicles that sit a lot is likely never to notice this "new technology" problem.
