For example, watching non-premium crunchyroll with an ad-blocker enabled is dishonest, IMO.
If we all start using audio adblockers, advertisers will then develop adblock detectors for podcasts. Then, it is likely we will get completely unskippable ads.
The only moral options are to 1) Power through the ads (or fast forward through them) so that you may listen to the podcast for free 2) Become a premium user to skip the ads (unfortunately this isn't always an option) 3) Don't listen to the podcast
The content creator is not rewarded by your extra effort. A lost view is a lost view.
It's morally grey, in my opinion.
If we can agree that:
1. Using an adblocker on services that offer premium versions (such as Crunchyroll) is dishonest
2. Going to the bathroom/looking away from the TV during an ad playing on Crunchyroll free is not dishonest
Then the morality line is somewhere in between there.
My philosophy is to always support the content creator in some way. To consume content while robbing the creator of their source of income (even if it's pennies) is dishonest, in my opinion. I don't have qualms manually skipping an ad I've already seen 5 times, and can quote buy heart, however.
...but if that option isn't available, that makes stealing ok? "Hmm, I like this podcast but I don't like the ads. There's no premium support option. Therefore... I will consume the content of the podcast without the ads."
I find this line of thinking a bit immoral, to be honest. The moral option is to not listen to the podcast. And before you jump on me asking if its immoral to go to the bathroom during a TV ad break, I'm talking strictly about algorithmic ad-blocking.
It would be like if I had a place setup where you can get a copy of one of my indie video games I've been privately developing after watching an ad. My place has no option to flat out pay for copies of my indie games. But... you really like my indie games so you decide it's okay to just walk in and steal copies of my indie games until I provide you with an option to pay for them.
