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?

You should be able to ask Lenovo for a refund if you've bought the device with this feature in mind and if Lenovo advertised the ability to watch 4K on your preferred streaming service.

If the device just happens to support 4k, you may be out of luck. You could try sueing the parties that are supposed to deliver the 4k content and have revoked the key, but I doubt you'll get much out of them.

If you rely on DRM, the media industry has all the keys. You're left to their whims when it comes to content consumption, and there's very little you can do.
