"The ACLU has long been strongly supportive of COPPA. It is an important first step on the road to universal baseline privacy protections that ensure that every American—young and old—has meaningful control over their personal information online. (...) The ACLU protects privacy and free speech simultaneously, and the two interests are rarely at cross-purposes. Right now, COPPA is a great law and it does both effectively."
