Many adblockers work by blocking dns resolution, which does not alter code. It's like putting on glasses which block out certain words of a book you're reading. No alteration of the source material or host.

I suppose if this comes to pass such glasses would be illegal. As they go against moral rights of the author.

And then color accessibility settings such as filters would be illegal when reading any colored material since they would corrupt the author's intent.

Does it apply to organic, individual differences in perception?

Maybe when we all get a neural interface we can be calibrated as per some industry standard profile.
