Although I get where you're coming from. It would also be nice if all products discontinued by google would just get open sourced.
They are basically saying it's useless to them so why not let somebody else give a try.
Video chat has been around since forever. Having a major player like Google wade into the fray, destroy all the small fry, then bail out (as it has done many times before)? Not good for the market.
Whatever small fry exists on the market, they have survived the Skype juggernaut, FaceTime, Google Hangouts and Facebook chat. I find it highly unlikely that Google Duo is going to be a uniquely destructive force.
Real-time video is plain hard, especially when latency comes into play. Having Google tackling this with their unique technology (QUIC / lots of low-level performance expertise) and resources (GCP / CDN), I'm really looking forward to try it out.
Their standard reason is that most products use tons of internal API calls/private modules and it would take a lot of hours to replace those with code they're willing to release.
The point is given the many, many other video chat apps that do already exist and fill this function, several of them produced by Google, what does Google think it's doing bringing out yet another one.

When I started using it a few months ago, the contacts discovery was a bit buggy, but it's worth a try. The feature set is quite rich.

First they deprecated SMS on Hangouts. Now they have replicated the video and voice portion. The next shoe to drop will be discontinuing Hangouts.

Give them a chance to collect more data first. Many governments might be backing this service.
