VPNs can help you to hide your traffic so that your ISP doesn't know what you are doing. You move trust from the ISP to a VPN provider. There are good providers out there. If you want to have a more trustless setup install your own VPN server which is pretty easy.

Here is a very easy script for the installation

Rent a VPS anonymous from us or choose any provider you want. But thats a much more trustless way.

Also you have the advantage that your IP isn't blocked by some services as it doesn't belong to a well known VPN subnet.
