My first DynaVap is the 2021 M. It's an awesome device, and today I've finally pulled the trigger and ordered an Armored Cap, as well as a glass stem.
At first I didn't use it much since I missed tabacco/nicotine from smoking spliffs. Switching to a single flame torch massively improved the experience compared to a triple torch flame, because the former results in stronger hits.
The only thing that I noticed that likely violates YT TOS is LTT mentioning alternate YT frontends, e.g. FreeTube, LibreTube, and Invidious.
This being enough for taking down a video, not just demonitizing, makes sense in the context of YT cracking down on third party frontends. How long until YT uses DRM?
