I guess it's just DNS level blocking. If you don't want any blocks, switch to Cloudflare DNS. If you want a customized experience, you can create a free NextDNS account which allows for 300,000 queries/month. It also has many pre-existing blocklists for ads and trackers. You can try that out for free without signup with a temporary 7 day account, just click on "Try for free".
