What do you call a site that one week says buy another week sell and then another week buy
I believe the idea is to give people varied opinions pro and con. You do not "pay" for the daily news stories that motley fool puts out. Those stories are written by DIFFERENT authors with different opinions within the organization. If you want confirmation bias watch the political cable channels.
The MF's "true" pay services do not change sentiments on a weekly or even a monthly basis. In fact they trade in and out far less than your average hedge fund.
