I had the same question, so for anyone who doesn’t want to dig through the article:
To defend its 2017 repeal of net neutrality rules, the Pai FCC argued that broadband isn’t a telecommunications service because Internet providers also offer DNS (Domain Name System) services and caching as part of the broadband package. A judge said the Pai FCC was entitled to deference on this opinion—even if it didn’t make a lot of sense.
Basically, Trump’s lackeys legally classified broadband as an “information service” to screw the American people and the question is whether the Supreme Court will go along with this blatant nonsense.
