Respectfully, repeating your desire for distros to decline to comply with this law isn’t a particularly productive contribution to the conversation. I understand completely the opposition to this legislation, which is frankly sophomoric in its imprecision regardless of how well-intentioned it may be. That said, asking other people and organizations to ignore liability placed on them by legislation is barking up the wrong tree. Your energy is better spent trying to get this legislation repealed or at least amended, especially because Newsom’s signing statement indicated there will likely be an amendment process.
So instead of begging distros to ignore liabilities, ask your friends and family in California, Colorado, New York, and any other jurisdiction that has passed or is considering this legislation to contact both their State Representative and State Senator. In particular, it would be valuable for these bills to be amended clarifying that they only apply to commercial ecosystems as described by @gbcox here, in particular an exemption for noncommercial and/or FOSS operating systems and applications would be valuable, to mitigate the chilling effects this may otherwise have on FOSS.
