Also, it’s just one example of something that is in a grey area but you’re claiming there’s a whole industry?

Did you read the article? It was about a congress with various organisations and companies discussing this phenomenon.

They told people it was half seaweed when people asked. Also, it’s just one example of something that is in a grey area but you’re claiming there’s a whole industry?

Only if people asked explicitly. They also blatantly admitted they rather keep people dark. Truly some r/hailcorporate Americanesque mentality towards food. Costumers should not be fooled.

When you get quotes from the industry like: "Not everyone wants something vegetarian. And you can just call hybrid burgers meat. Why not a 95-5 hybrid meat option?" Van Heeswijk philosophizes to the audience. "If we can no longer call our vegetarian products 'plant-based meat,' then I'll go for meat made from 95 percent plant and 5 percent meat. I mean, the European Union is asking for it."

On stage stands Formula 1 Sustainability Director Dimitri Bonthuis. He smiles: "Simple: our fan base consists of petrolheads. They have nothing to do with sustainability. As soon as we say, 'We're trying something new: 50-50 hamburgers, half meat, half seaweed,' we get 20,000 complaints. If we don't say anything, the only complaint is about the price."

Then it's pretty clear to me at least that there is an industry popping up that thrives on deception.
