I can see how McDonald's would make a strategic choice to lower their time to serve a customer in exchange for a machine that is broken part of the time. They actually track and chastise workers based on taking more than some absurdly short amount of time to serve a customer. It seems like a corporate strategy for them, and this is in line with that.
The employees at most McD's are in a different class than most other franchises. This isn't universal, of course, but for the most part, McD's hires from the very bottom end. This isn't bad -- I see people with Down's, strong autism, and similar working at McDs, happily, and those folks need jobs. To do that, you want equipment which is a bit more fail-safe.
Otherwise, we'd have safety issues at McD's every week, and they're exceptionally uncommon. That's because of a robust process. Ice cream machines with more fail-safes at McD's make sense to me.
The really incriminating part of the video comes at the very end, where they locked out Kisch.
His argument is that "big businesses protect each other", but that obviously doesn't make sense unless McDonalds owns Taylors.
They want their franchisees to have as much money as possible, that's what benefits them.
