One of the internet’s primary protections is on the verge of an overhaul. Section 230 — part of the Communications Decency Act — shields online companies, including tech platforms and publishers, from being liable for the content that others post to their sites. But, amid outcries over disinformation, hate speech and concerns about biased decisions to kick people off social media platforms, Democratic and Republican lawmakers alike have proposed changing Section 230 over the past year. The most recent reform proposal is the SAFE TECH Act, which was introduced on Feb. 5 by Democratic Sens. Mark Warner of Virginia, Mazie Hirono of Hawaii and Amy Klobuchar of Minnesota. The bill would make platforms like Facebook and Twitter liable when paid content posted on their sites is used to target vulnerable people. But some lawyers and media executives say the SAFE TECH Act and other reform proposals would remove legal protections that helped the web thrive in the first place.
