The price tag certainly has HN crawling, clearly without downloading and seeing how simple it is to use with only an email. Most prosumer companies play down the cost, and highlight the free trial. Given the "power user" nature of getting up to speed with Muse (video + 9 "tasks" to complete) it's worth trying to remove all friction from installs since you'll get churn from a subset even before prompting them about the price, due to the commitment someone needs to make with new habit forming and learning.
