You're talking about the streamers? As I mentioned, streaming is a tough business, it's going to have a lot of churn. In terms of viewership, there's publicly available data and it's not going down:
What kind of data do you have? Do you work at one of these companies and know that the data is fudged? Do you run an analytics company? There could be some measurement errors or biases but it's virtually impossible that it's directionally incorrect when we're talking about 67% growth y/y.
They're giving up on streaming because they hate twitch that much.
