This was ~three weeks ago, so I'm a little surprised I couldn't already find anything about it on the forum. Maybe I'm just bad at searching?
Anyway, Ron DeSantis posted the following around the same time as the Florida ban:

I suspect the real motivations are more ordinary protectionism, but it seems like potentially a sign that cultivated meat might start getting politicized / embroiled in the broader culture war, though also (perhaps surprisingly) DeSantis has had supportive comments from a Democratic senator (see Vox again).
I'm interested in the extent to which alt-meat startups and policy folk were surprised by this move – whether this represents a more hostile environment than we expected, or whether this was "already priced in". I tried to look at stock prices, but based on some quick searches only found one publically-traded cultivated meat stock STKH, and don't understand enough about the process of when the bill's passing became inevitable to really interpret it.

I think there is a very strong right-wing case to be made for alt proteins, i.e, “This is an example of how private businesses can solve climate change via capitalism and innovation”, and alt protein advocates should be making this case inside right wing political parties.
I agree this would be appealing to intellectually consistent conservatives, but this seems like a bad meme to be spreading/strengthening for animal welfare. Maybe local activists should feel free to deploy it if they think they can flip some conservative's position, but they will be setting themselves up for charges of hypocrisy if they later want to e.g. ban eggs from caged chickens.
