Your comment is ridiculous. If my purchase choice is guided by the vendor telling me something is a “lifetime” service then why shouldn’t I believe that? Why put scepticism above hard facts and a contract?
As it happens I bought one of these “lifetime” VPN deals for $40 a decade ago and have had a great deal of use out of it. I bought it because it was advertised as a “lifetime” deal and I’d estimate it’s saved me around $1400 over a subscription VPN service over that time. And it’s still going. I must be dreaming.
