Kids are being harmed and are harming others online. Parents (imperfect as they may be) have far less ability to intervene than they do in physical spaces. Technologies (and technologists) are a major cause of this autonomy.
If we build technology that leads to harm, it increases the chances that a law like this is passed. Doesn’t matter if we meant to. The primary role we have to prevent legislation like this is to think creatively on how what we build can help create a better world in many aspects that are largely overlooked. Otherwise we’re feeding the political capital of bills like this.
Want to preserve the current internet? Don’t settle for the current societal impacts. They’re unacceptable and politicians will have to respond, and will do so the only way they know how.
