Who Owns Your Wireless Service? Crooks Do. (2019)

There's the privacy and data protection task force[1] doing things like amended rules to combat sim swap fraud[2] (which I think only came into force this month?)
There's the robocall task force[3] with what seems like a mostly successful push for STIR/SHAKEN implementation[4] though maybe some small providers are still given extensions[5].
Granted, the Supreme Court has been poking hard at executive rulemaking capability so some stuff may not survive. Net Neutrality just had a temporary stay in the 6th Circuit.[6]

Trump: Ajit Pai (https://en.wikipedia.org/wiki/Ajit_Pai)
Biden: Jessica Rosenworcel (https://en.wikipedia.org/wiki/Jessica_Rosenworcel)
For Rosenworcel, her primary focus seems to be a focus on restoring Net Neutrality. For Pai, his primary focus was on its repeal. The two both share a focus on broadband access and marketing radio spectrum. In terms of banter, Pai is certainly more of a "the free market" personality, and Rosenworcel is more of a "top-down regulation" personality.
Regarding impact, I would characterize their offices as substantially unique only in the context of Net Neutrality.
