Yep, and Filoni spent an entire season of Clone Wars exploring why Yoda would be more open-minded and flexible on Jedi orthodoxy, made sure his appearances on Rebels are consistent with that character arc, and then turn around and writes this crap... It also makes no sense why he also threw poor Ahsoka into this crap too.
I can't believe that the same lady who broke half of the Order's rules with her master, rejected the Order as corrupt, hung out with Kanan and Ezra, and finally, decided to sacrifice her life trying to save her Master out of attachment, is now coldly regurgitating Jedi orthodoxy about attachment.
