Wireguard to where? Another ISP/VPN that can also sell/MITM your traffic just as well? Non-residential exit IPs are also very often blocked by many websites.
Entire businesses specialize in this; Nokia and Kentik.
Trying to use a VPS/cloud IP or well-known VPN provider, the experience for me is just as bad or worse.
For some, the issue is a lot worse than you think.
