None of it was binding or involuntary. Which is why Apple never released a micro-B phone and all other manufacturers were able to upgrade to USB-C.
Maybe you think the original nonbinding agreement had a threat of force behind it, but it had no immediate consequences if manufacturers changed ports. Manufacturers were allowed to upgrade to new ports. And they did. That is how we got the innovation of USB-C.
Manufacturers are no longer able to upgrade to better ports. People saying "this won't stifle innovation because we still got USB-C" have things totally backwards.
