Live Streaming Stock Data?

There are a lot of Youtube live streamers who show live market data on Youtube. I'm considering getting into it but I'm unclear on the legality. I want to live stream both futures and stock data, and live trades. If I ask chatGPT, it clearly tells me that doing this is illegal. Does that mean Patrick Weiland (for example) and the other 999 live streamers on Youtube are redistributing illegally, and it just isn't being enforced?
