Here's a gold mine that will pay out for years, perhaps decades. Let's nuke the mine and get an extra 1/5th on the first payout, sacrificing all future gains. Real smart there boys.
Someone downvoted me. Probably didn't get the analogy, so I'll spell it out. The gold mine = a subscriber. The nuking of said mine = fleecing the subscriber on his/her first payment and thus losing the subscription.
