Yeah - on one end of the spectrum you have stuff like that or white people wearing native american headdresses, both of which are in pretty poor taste because of the bigger picture they both evoke.
On the other hand you have folks on Tumblr screaming about how folks learning non-native languages is awful. Engineering techniques I think tend to fall pretty far on the side of ‘perfectly fine to cross boundaries’, because of the nature of the work and all that - they tend to be practical solutions, or even artistic, elegant solutions, but not necessarily spiritual or cultural touchstones that can be disfigured or disrespected in the same way that like, a tea ceremony could. At the end of the day, any joinery is designed to hold wood together and is derived from a place of practicality.
