I imagine they’re just releasing everything at this point so they can show the total number of hours watched to investors, who I would guess will also be very interested in the numbers as a benchmark for valuing streaming services going forward.
Suits (2011) for example is not a Netflix original, yet it made it into their top 10 by hours viewed.
Others mention that this is a result of the WGA strike, though apparently the terms of the deal allowed the streaming company's to require an NDA to view the information, so that doesn't explain everything.
It seems not, as from a bit of cursory research, Netflix did not produce Chiquititas (2013), Paw Patrol, Wrong Side of the Tracks, CoComelon, Extraordinary Attorney Woo, Suits, Breaking Bad, etc.
For some of these they may have exclusive distribution rights, but I don't think any of those are Netflix Original content.
