Is there an opt-out mechanism at least? CF is burning goodwill in months it built over the last decade.

Yikes! I see this too:

<script type="module" src="https://static.cloudflareinsights.com/beacon.min.js/v4513226..." integrity="sha512-ZE9pZaUXND66v380QUtch/5sE9tPFh2zg45pR2PB0CVkCtOREv2AJKkSidISWkysEuQ0EH8faUU5du78bx87UQ==" data-cf-beacon='{"version":"2024.11.0","token":"c0859b51a7804ab5a9cc8e9e2b2c4cde","r":1}' crossorigin="anonymous"></script>

Took me a minute to realise this isn't 1.1.1.1 (which Cloudflare also runs), but their original website DNS hosting service.

Yes, they add the js if "web analytics" is enabled. I believe I had to manually enable it on my old sites though. Maybe it's enabled by default when adding new domains?

Isn't this well known when using CF as a proxy? Not sure how they would provide traffic / DDoS telemetry otherwise.

yep, last website I did was JS free 100% except that pesky cloudflare script

You left out the part about how you use them as a reverse proxy, which is decoupled from DNS. One is coincidental; the other required.

If they can inject script, they can also snoop on all your cleartext traffic without you knowing....

To add to your experience: It was also very hard, for me, to find the setting that disables this JavaScript.

Surprise! The man in the middle man-in-the-middles! This is only the beginning, when you’ll get used to this they’ll do worse and worse, enshittification, remember?
