I was introduced to Tantacrul via his video on MuseScore. I was thoroughly unimpressed by it and was taken aback by the things he chose to focus on and give priority to.

A lot of the video felt like it was missing the forest for the trees and felt like more like a person trying to say "Did you notice this? I did!" rather than focusing on the actual big picture.

At one point he says that software should try to build on familiarity and frameworks that the user would be used to and find intuitive. Later on, he completely misses how presets are represented and complains that it's unintuitive.

The amount of time he chose to spend on iconography was mind-boggling, and his specific comparison of of iconography to typography was tenuous at best.

Overall I feel that the lack of of FOSS UX devs is what Tantacrul is taking advantage of. His slick videos seem compelling and correct, but are extremely surface level.
