There’s a curious thread connecting Robinhood, Facebook, Twitter, and Apple this year: The technology companies are starting to take active responsibility for what happens on their platforms.

From Robinhood Markets Inc. deciding to limit trading of meme stocks, to Facebook Inc. and Twitter Inc. banning then-President Trump’s accounts, to Apple Inc. rolling out tools that make it harder for app makers to hoover up user data from iPhones, the platform operators have taken steps that extend beyond their legal obligations. It’s an effort at accountability they have generally avoided.
