With Reddit shutting down its API setting a precedent in the corporate tech world (and Reddit was a major outlier in that a ton of their users are technical minded and support third party clients, YouTube does not have that kind of userbase and will not get backlash for it), Twitter doing whatever the fuck they’re doing, and Google already hellbent on destroying ad blockers, the days of Newpipe, Invidious, and Freetube are numbered. Wouldn’t be surprised if they implement Netflix level DRM tomorrow that makes alt clients impossible. I say savour your alt clients while you can guys, you won’t be able to soon.
I suggest subscribing to YouTube via RSS (yes, YouTube still has an RSS feed for channels and playlists). I’ve been doing this for years and it works great. You can use your RSS reader or an add-on like Livemarks to discover the feed.
If you subscribe via RSS, you can then easily substitute the feed URL for any other platform, if the creator happens to upload their content to platforms other than YouTube.
Even though the videos are hosted on different platforms, you still have a single feed in a single location with all new videos thanks to RSS. You’re also able to manage a “watch later” list with your RSS reader.
