Apple has far less to do with USB C’s adoption than the tens or hundreds of millions of Android phones. Once peripheral makers etc are already have in house experience and knowledge with USB C thanks to their phone departments, it makes far more sense to release USB C peripherals even at the desktop level, so the removal of USB A ports from the MBP likely played a very small to no role in the transition. Even if the MBP had both USB C and USB A ports, peripheral makers would likely have preferred making their peripherals USB C compatible.
