I mean, I'm as much a cynic as anyone, but I swear that these days it seems like Google can't catch a break on this site.
Maybe there is something to soaking up a market (RSS) then dropping it (though it seems the ball is being somewhat picked up there), But, maybe unlike walmart?, there is little reason to believe that was malicious. People (Kevin Rose, for example) were making fun of RSS being super dead in 2011. I am no expert, but I doubt it is a google plus play as much as a twitter defeat. Note: I personally love RSS, but if I was not a tech news junkie, it might be of little use to me.
Hangouts is becoming a nightmare of a proprietary locked in mess that is destroying decades of progress in FOSS space towards open standards for communication. They are killing Jingle and XMPP by depreciating Talk, and they are now killing VNC. They may not have played nice together, and they may be painfully outdated, but it isn't an excuse to take your toys from the community sandbox, go home, and build yourself a space rocket in your back yard and fence it off, because very few people will pay to get in your back yard and will stay in the sandbox with Tonka Trucks.
Um, no. This feature substitutes for one small VNC use case -- a use case already largely controlled by commercial products like TeamViewer and Copilot anyway.
VNC has much broader uses than this.
As of two or three weeks ago, the Hangouts videoconferencing code used WebRTC, Jingle, and a variety of video and audio codecs (among which one could find Opus.).
If you run the software on a *nix system, you can verify my claims by checking the contents of /tmp/gtalkplugin.log while you're in a video call with someone. Note that that file seems to be flushed to disk at irregular intervals, and that it is removed after the call is terminated.
There is still room for others, especially in the spheres where using Google products is not an option.
