The so-called 'double standard' in AB-587 (defining 'social media platform') is entirely consistent with the existing federal 'double standard' set up a quarter-century ago by Section 230, which makes providers of 'interactive computer services' immunity from liability for content moderation decisions. This bill can be seen as oversight layered on top of those existing content-moderation liability protections.
If you want to tilt at 'because computers' windmills, Section 230 is the real target.
