> The California Supreme Court held the individuals had the right, under state law, to engage in the proposed activity. The ruling did not compel the shopping center to say anything at all, and the ruling did not prohibit the center from saying anything it wished, when and how it wished.
And it doesn't apply because:
> FAIR and PruneYard establish that compelling a person to allow a visitor access to the person’s property, for the purpose of speaking, is not a First Amendment violation, so long as the person is not compelled to speak, the person is not restricted from speaking, and the message of the visitor is not likely to be attributed to the person. The Florida statutes now at issue, unlike the state actions in FAIR and PruneYard, explicitly forbid social media platforms from appending their own statements to posts by some users. And the statutes compel the platforms to change their own speech in other respects, including, for example, by dictating how the platforms may arrange speech on their sites. This is a far greater burden on the platforms’ own speech than was involved in FAIR or PruneYard.
