Agreed that a monthly data cap is stupid for a VPN, because to your point, bandwidth and number of simultaneous connections are the real constraints for a VPN service, which is why most VPNs limit connections and bandwidth. Limiting these does effectively set a monthly data cap, though, and you won’t be torrenting a petabyte a month for $5 no matter what. “Unlimited” is bullshit either way and it’s best to understand what the limits are and how they’re enforced.
Sounds like an all “you can eat” buffet with king crab legs that you never get because assholes keep taking them all whenever a new batch is put out. If it hasn’t devolved to that yet, then enjoy it while you can.
