Yeah, I would say it only makes sense to use a trusted VPN after you did all you could to protect from tracking on your devices. Mullvad did some work on using TPM to create cryptographic prove on what is running on their servers… so there may be a way to have extra transparency on the VPN providers but we are not yet there. So using VPN moves your trust from ISP to the VPN provider. It will also make some sites/services to block you or require extra validation.
