I thought the difference there is that they were upfront about the feature in Knox and you can still install another OS, it just disables Pay and the Secure Notes part. Also it was something there from the start.

This feels markedly different as it’s retroactive and a full brick, which is much more severe and a bait and switch.

Why would they start with the harder one? Samsung is much better funded, and therefore will be a much more difficult case.

And no, it does not matter that Samsung did it first.
