I'm fairly sure SLS didn't want to kill off the free members as a result of a business model change, but they did it because of that stupid FOSTA law. They had a successful business model with limited free members who would, if they stayed in the LifeStyle, probably become paid members. I suspect that their revenues will slowly fall because they'll have trouble attracting new paid members.
On a similar note, they put out a new policy today that says that ANY mention of payment, even for things like house parties, will be taken off. Stupid FOSTA law . . .
