While you own the physical media, you don't own the data on the media. You only have a license to use that data and part of the license is not skipping ads, etc.
In the US maybe... excpet that TFA's lawsuite happened in Germany, EU. European country have their copyright law siding a little bit more toward end users than USA.
Among other, several country have the local DCMA-equivalent law, explicitely granting excetion for fair use. And explicitely consider "fair use" to b0rk the encryption for "technical reasons" such as needing to be able to play your own media because you buy it and want to play it and the manufacturer doesn't support your OS. (e.g.: Switzerland, although it's not *EU*, just geographically in Europe).
deCSS is considered lawful here: you bought the CD, use whatever you need to exercise your fair use rights.
There's no concept of "you're actually just renting the data and thus must follow the license in order to be able to consume it".
It'd be akin to requiring a login to use a free website, but the agreement for the login to say that you accept the ads in order to use the website.
Again, in most european countries, EULA aren't considered binding. You can't sell your soul just because there was a sentence hidden somewhere in the big pile of legalese.
The only things which *are* legally binding are the general provision covered in the law itself (warranties, etc.)
But a website owner CANNOT sue you because you violated the license you were supposed to accept and used Adbock anyway.
On the other hand, nothing forbids the owner to kick you out and ban your account either.
