alt Hacker NewsIs this a Chrome/Edge thing? Or do privacy respecting browsers also do this? If so, it's unexpected.
If Firefox also leaks this, I wonder if this is something mass-surveillance related.
(Judging from the down votes I misunderstood something)

From what I understand, sentry.io is like a tracing and logging service, used by many organizations.
This helps you (=NAS developer) to centralize logs and trace a request through all your application layers (client->server->db and back), so you can identify performance bottlenecks and measure usage patterns.
This is what you can find behind the 'anonymized diagnostics' and 'telemetry' settings you are asked to enable/consent.
For a WebUI it is implemented via javascript, which runs on the client's machine and hooks into the clicks, API calls and page content. It then sends statistics and logs back to, in this case, sentry.io. Your browser just sees javascript, so don't blame them. Privacy Badger might block it.
It is as nefarious as the developer of the application wants to use it. Normally you would use it to centralize logging, find performance issues, and get a basic idea on what features users actually use, so you can debug more easily. But you can also use it to track users. And don't forget, sentry.io is a cloud solution. If you post it on machines outside your control, expect it to be public. Sentry has a self-hosted solution, btw.
