As I said in an earlier post, that sums it up, yes.

With one last proviso, in that let's hope they never put out a update 
that triggers an existing bug in your firmware that bricks the drive.  
Unlikely to the point of nil, but not entirely impossible.   It is the 
unforeseen consequences of a "self annealing" DRM that concern me.  
Since they clearly have not tested every forced update on every model of 
player/drive, the results cannot be predicted with 100% certainty.

It is correct in that it does not modify the firmware that operates 
equipment specifically, ie the controller.  However, BD devices 
themselves  retain disc keys in the form of flash storage in the 
player/drive's electronics.  If the studios revoke a decryption key, the 
player is essentially "bricked" for  playback of anything that uses that 
key.

Yes, that is why there are no "end all" solutions to BD playback with 
unsanctioned players.  Developers of things like makemkv are playing a 
tug of war with the studios.  Pointless, really.  BD was deliberately 
designed for this outcome.  If you want proper BD on Linux, you will 
have to buy a license and develop a sanctioned player - which means it 
would not be FOSS.
