With a VPN your origin and destination are visible to your VPN provider. You're just moving the point where your metadata can be grabbed. I don't particularly trust my ISP, but I don't see a reason to trust any VPN provider any more.
I mean, I generally trust Mozilla + Mullvad a lot more than Spectrum. The only reason Spectrum wouldn't be selling or otherwise mishandling every bit of data about me they can is if they're too incompetent to realize they have the data. Mozilla has a good track record; they could always become compromised or make other mistakes, but Spectrum fucking sucks.
