Are you sure that endpoint is sending all traffic to opencode? I'm not familiar with Hono but it looks like a catch all route if none of the above match and is used to serve the front-end web interface?

That linked code is not used by the opencode agent instance though right? Looks related to their web server?

They don't. That is just the route for their WebUI, which is completely optional.

I've point thought about making things that just send garbage to any data collecting service.

You'd be surprised how useless datasets become with like 10% garbage data when you don't know which data is garbage

Does opencode still work if you blackhole the telemetry?

this is a big red flag
