Indeed, not all VPN service providers have bad intentions. However professionally, they sell the service. They get money through paid VPN services. This means they are bound by trade ethics.

If we choose a free VPN that is naughty and this happens, yes we ourselves are affected by the negative effects and will definitely lose.
