In a nutshell, Blumenthal engages in grandstanding.

In 2009, as Attorney General, he grandstanded about former criminals using a social network, even if they weren't committing any crimes.

In 2017 / 2018, he was grandstanding about prostitutes on Backpage.

In 2019 / 2020, he was grandstanding about EARN IT. Even though it's an absolutely terrible idea.

In 2022 / 2023 / 2024, he was grandstanding about KOSA. He seems to be talking particularly bad nonsense about "AI" too, so better watch out for him.

I'm sure you could find more instances in the Blumenthal collection. What does it all have in common? Well, his ideas are unconstitutional (and harmful).
