alt Hacker NewsI can read Wikipedia too. All the calculations are done in m, s, g, etc. if you want to dumb it down to the public you might as well go in miles per hour, leagues per day, etc., spaceflight is not the place where it is appropriate.

Presumably you can also read the official BIPM SI Brochure. As mentioned, it will tell you the same thing:

2. When you ask the regular units police (BIPM), their official decision is that hours are "accepted."
I trust you can read the dictionary definition of "accepted" all on your own.

The blue origin launch this week used mph and feet of elevation, and I can definitively say that using modified SI is way way better than US customary

But, a video stream meant for the public consumption is. SI are standardized for the context of calculations, not necessarily for human consumption, which happens to be why nobody gives the weather in degrees kelvin.
