According to the page, it seems they wanna use their own servers for it.

I’m curious how well their own servers will handle that load, like sure they are used to web traffic but, there is a pretty big difference between downloading files and searches, and an always on VPN. I would expect traffic load to be way higher with the vpn. Granted the monthly cap will mean most will likely just only turn it on when needed like how samsungs free vpn was operated, but still.
