Mainly due to the fact that serious gun-control advocates are usually aware of how firearms work and how loose restrictions on who gets to keep them and why translates to increased incidence of firearms-related violence and death. As we see in countries where that advocacy has been translated into law in the form of sane restrictions, that ends up with demonstrably better outcomes for society in terms of shooting deaths.
In contrast, politicians who don’t understand Internet technology and network effects (and who tend to willfully ignore the real root causes like monopolistic corporations and their business models) generally make things worse for society when they take it upon themselves to rush through this kind of legislation on Internet-borne speech.
[now that we’ve cleared that up, a reminder that this isn’t yet another gun-control topic, however much some would like it to be]
