I didn't see a single person mention this little tidbit of what really drove that don't warm up statement.

It's not about your car lasting it's about getting that car to operating temp as fast as possible to drop emission levels. The cat will never get to operating temps in a cold climate at cold idle when the engine is running a rich mixture. That statement was EPA driven.

The owners manual on my BMW k1100 motorcycle that's equiped with a Cat point blank warns of damaging the cat by long warm ups before driving.
I wait till I'm up to at least 80f on the scan gage and thn I slowly drive out of my hood Trying to keep the RPMs down while the oil is thick. Thick oil will be bypassing
