I can say without a shadow of a doubt..
..that I feel no guilt at all. If sites put in a hard block then I simply won't consume the content. Most of it isn't worth the time it would take to bypass the block. Any content that I really want, I'll pay for (usually in the form of books or streaming services).
I'm certainly not poking holes in my ad-blocker for the sake of the usual drivel put out by most journalists.
The advertisers and content creators need a bit more imagination in their revenue creation methinks.
