I'm very glad to hear that this is the case, as the developer experience for streaming via Mux looks awesome - much less of a headache than building out a transcoding/delivery pipeline with separate transcoding APIs, object storage, and CDNs.
I'll be giving the Mux streaming API a try for my next project.
Yes, Reddit is a customer, but they use Data (our quality of service analytics tool), not Video (our suite of video streaming APIs). So...it's our fault if they don't have visibility into you having a bad time, but we aren't in a place to actually fix it quite yet :)
