The repo readme is pretty telling - this is being leaked to force this particular key to be blacklisted, I guess one group annoyed with others and wanting to cut off their access (and presumably the leaking group already has other L1 keys so doesn't fear this key being burned...)

or they had the skills to just dump it again

Edit: nvm I understood which key you were talking about. I would have replied, but I'm rate limited.

Ah, I thought L1 keys were burned into hardware, so blacklisting this key was effectively blacklisting a bunch of Lenovo tablets from accessing 4K HDR streaming?

Edit: looks like I'm wrong about this, and the Widevine L1 keys can be changed with a firmware update. There's an interesting breakdown of how it works on Qualcomm chips here: http://bits-please.blogspot.com/2016/04/exploring-qualcomms-...

Does this mean if I have a lenovo tablet that currently streams 4K, that it will lose 4K video support? Could I ask Lenovo for a refund?

Yes and yes. Lenovo probably doesn’t give a shit, though. But you can ask!

Depends on the country. Some do have some liability on manufacturers and/or vendors for defects. Unsure if an asterisk in their click through contract about key revocation would even matter.
