Feb 2017, it's released as "iYTBP", Injected Youtube Background Playback. It's a mod meant to make YouTube better. It gives you all the features of YouTube but for free. A piracy app, and a good one
This keeps on for five good years, without a peep from Google.
On the anniversary, Feb 2022, they released an NFT to try and make money off of it.
BAM. Cease and desist :)

I'm so disinterested in NFTs that I don't even care enough to sneer at them, despite the bros spamming a lot, but this is hilarious.
