Remember when there were scandals in the early days of digitization where redacted government documents were easily revealed because the redaction was performed by layering a black rectangle on top of the PDF text? The text was there to read for anyone savvy enough to remove the rectangles. The solution, of course, was to remove the text from the PDF altogether. Paywalls are a similar sort of measure: if publishers don't want their content to be available without payment then they ought not serve it publicly. Similarly, if they don't want users using adblock then they ought not serve the content to those who fail to load the ads. Is it ethical to bypass flimsy DRM? The bits are on the user's computer and are processed by the user's software at the user's discretion. Publishers _may_ have no right to exert control upon the user's property; and I suppose whether they do is the crux of concern.
