Probably not on purpose.
Well-meaning individuals seek to learn and teach tai chi.
Unfortunately, they have no real idea what tai chi is or what the training constitutes.
Instead of adhering to a long-term commitment of training, practice ad study, the person looks for a shortcut.
They seek something that fits their own idea of tai chi.
Consider the old adage: "There's a sucker born every minute and two to take em"
There are disreputable organisations that will take advantage of naive people.
Maybe they are simply giving people what they ask for... but this is not tai chi.
