how do you block them in an app like warp ?
See my other comment for what I use, TripMode, but a DNS block on *.sentry.io would block the sentry calls. I tried setting a proxy to see Warp's other network activity but only the sentry.io calls actually respect the system-wide proxy settings. Pretty annoying, though it's probably not intentional. Just takes a little more work to inspect its traffic.
Other DNS lookups it triggers:
api.segment.io
app.warp.dev
identitytoolkit.googleapis.com
o540343.ingest.sentry.io
securetoken.googleapis.com
storage.googleapis.com
I'm in this boat. I never understood why I should care if some website interacts with google apis or logs everything I do and sells it to marketers so they can sell me ads. I'll block them anyway so it'll never make a difference to me one way or the other.
