> It's my understanding that NN only applies to wired carriers. Wireless was exempted from NN.
Your understanding is wrong on several levels:
(1) Net neutrality is a common name for a set of principles that predate (even as an official guiding philosophy at the FCC, though the FCC consistently used “Open Internet” instead of “net neutrality” as the name) the 2010 and 2015 Open Internet orders, and as such apply equally to all carriers.
(2) The distinction made in the 2010 and 2015 orders was between mobile and fixed carriers, not wireline and wireless.
(3) While much weaker rules were applied to mobile carriers in the 2010 order, that wasn't true in the 2015 order, and in any case both orders applied to both fixed and mobile carriers.
Although Net Neutrality under the Obama admin only narrowly applied to wireless carries, one of the things that applied was discriminatory blocking/slowing downs of specific content (if I remember correctly).
