I love Chromecast on vacations for the same reason: I can continue using my subscriptions without logging my account into the hosts TV.
The one difference is that Google TV runs the app for service if installed and streams with that. It is nice to use the remote when streaming instead of pulling out phone to pause or change volume.
I understand that, but the new Chromecast devices and presumably the devices replacing them require you to log into the device before you can even use it as a Chromecast stream destination, and then when the video is done instead of going back to nice photos they try to shove algorithmic recommendations in your face. I want the old Chromecast back.
Just to try, I just logged out of my Google Chromecast with Google TV (yes folks, it may time to rebrand...), and started playing a stream from Spotify using my phone.
And now I'm listening to Spotify.
I did this with both Google Cast and Spotify Connect (Spotify, at least on Android, allows selection of this).
No issues.
Am I not holding it right? It sure has the appearance of working correctly, but we may not be observing the same things.
The old Chromecast experience -- choose media on phone, play on TV -- is all I ever wanted. I hate using a remote to browse -- my phone is much better. I hate having my TV logged into an account -- my family, kids, guests all use the same TV and I don't want them using my account, nor do I want to see their account when I'm using it.
The Chromecast protocol is the only thing that the entire ecosystem of Android streaming apps integrates nicely with. I wish Google would open it up to third parties to create Chromecast-replacement devices... but of course they won't. They aren't doing what's best for users, they are doing what's best for their engagement metrics and revenue. And thus, our experience actually gets worse.
