Why is DRM necessary? In the EU, many countries mostly just use digital watermarking for their native language e-books bought from stores (e.g. Germany and the Nordics). We got the music industry to get rid of DRM on music files. I'd argue watermarking is enough to discourage people, and no matter the DRM or no DRM all books still find their way to shadow libraries. I agree, as Terence also argues, that this is a very non-intrusive DRM, but which still has many problems of.. just being a DRM solution for one. The licensing fee to allow support for LCP is also absurd, and ranges from a few thousand USD to tens of thousands. There are therefore no FOSS apps capable of supporting the DRM, like KOReader or Librera. The solution in itself is not fully FOSS either.
And aren't you annoyed by their arrogant tone and how they try to blame, guilt, and threaten their way forward?
I've never tolerated alcohol well so for me it's just as bad now as it was when I was a teen. I just get sleepy which makes me want to go home at 12 and the day afterward I spend half my day puking, even after just a couple of beers.
