As a content creator you have full access to all of these metrics and when the average ASMR stream is making hundreds or even thousands of dollars less than other content it becomes a clear choice. The algorithm also hates it, and you need to be careful it doesn't decide that your whole channel is advertiser-unfriendly and basically ruin your income.
ASMR can make sense when your channel is small since it ysos into a captive audience to help push growth, but once you have a stable viewer base there's just no good financial incentive to continue with it.
