It's just lazy design, or possibly malicious, I'm not sure.
It's a low-class business model that is rife with disease. There's no barrier to entry-- literally anybody can do it, there is no filtering of who they'll do business with, and it's a race to the bottom to earn pennies at the expense of their integrity. Despite having actual content of value, they share a business model with a blog farm full of Markov-generated malware-laden shitposts.
Given the now-well-known threats to health and safety that third-party ads present, one does not have the right to get upset when clients insist on using protection when dealing with them.
Set up a Patreon for donations, set up affiliate links or offer subscriber perks if adblocking is cutting into revenue. Either option is far more lucrative, ethical and honest than whoring oneself out for the benefit of some shady ad firm that leaves the user with a nasty case of Bonzi.
Not our problem if they bet on a brittle business model and don't want to adapt. Even more: the web ecosystem was fun and a with a lot more freedom before the invasion of ad based companies. I don't see any problem with some culling of the politically correct parasites.
I cannot make myself care about that, at all.
I am not the person responsible for finding a viable revenue model, that is the responsibility of the content creator. I refuse all ads and tracking, because I value my own attention span, my time, my bandwidth and my privacy.
I am not obligated to watch ads online, just as I am not obligated to stay on a TV channel and stay in the room while ads are running, just as I am not obligated to pay any attention at all to ad billboards.
As an aside, I support several high-quality content creators through Patreon, and several open source projects through donations.
I think you are aware that ads are the emerged part of the iceberg, the big part is the profiling, tracking and data collection going hand in hand with ads.
If ads were unintrusive and not gobbling privacy, then I would not block them as I would not mind them.
Excuse me but I have to go now, local girls want to give me a free ipad that I won by clicking the fart button after subscribing to the newsletter that was blocking the content of the page I finally chose not to read because fk it.
