As the article notes the largest meat packers are at least somewhat against this and are themselves investing in cell grown meat. The National Cattleman’s Association stance on the issue, also noted in the article, boils down to “It’s fine, it just needs to be labelled so consumers know what they’re getting.”
I think the only “they” we can define here are the Florida and Alabama State Legislatures.
If I was a Rancher, and I’m not terribly far removed from that, I wouldn’t want cell grown or cultivated meat banned. I’d stand up a production center for it on my ranch right next to my cattle and sell both.
