It increases the cost and complexity of an ISP tracking you, which is a win within itself. Plus some services share public IPs or are behind a global cache (e.g. Cloudflare) making it harder to pinpoint exactly which endpoint you tried to access. Is it perfect? No. It is better than yesterday? Yes. I call these "micro-wins." One micro-win won't make a difference, but two, three, four, and so on eventually start to have an impact. And that's all we can hope for. Even often cited VPNs just shift the problem downstream. Instead of your ISP monitoring you, the VPN provider themselves could, or if you host it yourself then your server/virtual server's ISP could. VPNs themselves are another "micro-win" but people often claim they're a complete bulletproof solution.
