This is a crazy proposal and destined to be an unmitigated disaster. However, I recently had a realization: Did the politicians behind this proposal come up with it, because they were inspired by the bright-red "dangerous website ahead" pop-ups in Chrome and similar?
It's dumb from a technical standpoint, but arguably, web browsers set a precedent already for being capable of censoring by URL. In which case, did the "we'll just censor phishing websites" turn into a "slippery slope" in the minds of politicians that led to this?
