Yeah, you're probably right. I couldn't find the text of the bill in the link. I'm sure the effort to do this kind of thing goes back to the 90s: like a lot of the really intense copyright bills - the CASE Act (ability for big companies to easily fine people who they think are breaching their copyright for $5,000 + legal fees without anything resembling a trial or evidentiary hearing) has been popping up in different forms for decades - but in its current name they took 5 years of trying to pass it, but the main idea was officially proposed in 2006 - so 14 years to get the bill passed, but then it was a thing long before it was officially proposed by a house comittee too.
I guess they figure if they keep trying they'll eventually get it passed - which is probably true.
Most of these "online safety" acts have been sitting around in congress for half a decade at this point. Mike Johnson keeps blocking them because he has serious doubts about their constitutionality (which keep getting borne out whenever the laws end up in court).
