There is way too much incoherence and righteous indignation in this comment for it to be the top thread here.
> "full ownership" - of what?
By a reasonable and charitable reading: full ownership over your legally-obtained copy of the material that folks (the creators/rightsholders themselves) are publishing for gratis online for anyone to watch, and likely some non-gratis stuff that you are paying these creators for if you are a subscriber and decide to enter your account details into the app.
This whole app looks to be a video player that works like an alternative frontend to the official players by e.g. YouTube, Twitch, and so on, in the vein of "unity of interface"[1] and a continuation of the spirit of the Miro player (see also: virtually every podcast app in existence).
You seem, bizarrely, to be responding to it like a new KaZaA or Popcorn Time or other torrent-backed something-or-other.
