The shitmydadsays guy has a million followers, but their level of loyalty is pretty low. If he all of a sudden stopped posting occasional funny shit his dad says and started posting "Special offer on new Sprint cellphone plans!" and "Hey, have you heard the good news about Jesus Christ" then he'd find himself low on followers pretty quick.
On the other hand, a band of followers who think you're awesome and really care about your opinions on things is extremely valuable.
Not at that scale it doesn't. As I said, if I actually had billions of followers, there's no way I wouldn't be able to extract a huge amount of value. I might destroy my following in the process, as you point out, but not before I got rich ;)
But if they really care about your opinions on things and you start posting good news about special offers on Sprint Christ plans, then they will cease to care really quickly.
If they care enough you may be in for some hate mail.
