This is honestly the most frightening thing to me. Even if prevailing opinions change, they can't bring these regulations back in the future? This seems...majorly problematic.
Edit: The Ars article [1] expands on this a bit further:
> The Senate today used its power under the Congressional Review Act to ensure that the FCC rulemaking "shall have no force or effect" and to prevent the FCC from issuing similar regulations in the future.
I'm not well versed in the Congressional Review Act and what its invocation means here, but I've seen commentary to the effect of "The FCC won’t be able to try again, even if Congress gets back on board".
