The US had its own version of authoritarianism taking over the internet when its telco monopolies started insisting that heavy users pay more for their internet connections. That was subsequently reversed but it lead many to question if the US was really up for any involvement in administering the internet and it should be left to a more neutral, more democratic country to run.
I'm glad they mentioned is, the PRC and Russia are certainly unfit to be making rules for global internet for the reasons mentioned (an internet where it's illegal to be gay? no thanks), but a USA representative is also unfit imo because they'll just represent Comcast et al, who are provably terrible stewards of internet freedom.
