If you offer content for free I'm not going to pay for it. I don't tip, I don't buy micro transactions in games, I don't pay for discord nitro or buy "collector's edition" versions of games or twitch subscriptions or anything like that.
Simply, if I don't have to pay I don't. And I certainly won't waste my life watching ads just so someone can earn a fraction of a cent.
I don't feel any need to justify that, I don't feel bad about it. These tactics earn tons of money, and if that ever stops they'll stop doing it and do something else instead. Until then I'll happily take advantage of all the free stuff. Someone else wants to donate to subsidize me that's great, go right ahead. I'm gonna keep my money.
You justify with 'if you offer content for free, I'm not going to pay for it'. Agreed with microtransactions and stuff. But with youtube videos? The content is not actually offered for free. It precisely relies on ads to exist. So the content is offered with ads/with subscription (i.e. not free), and you are using an adblocker to bypass this. So you are just leeching out of the other users, and is not sustainable.
As long as I can use youtube for free with an ad blocker (and sponsorblock, amazing plugin) I will. If google doesn't like that they better figure out a solution. Not my problem.
The thing with ads is: it's not free money. We pay for it. All of us. It's part of the price when we buy goods and services.
If advertising wasn't possible, items would be cheaper and we would have more money to pay for content directly. Cutting out the whole advertising industry out of the content payment loop would save so much money.
And yeah people would still buy stuff they need because they need it. And stuff they didn't need? Well good then that they're not buying it. Saving natural resources and money.
For videos and podcasts I subscribe to content creators on Patreon. I currently have four subscriptions for a total of around $12, and I give roughly the same amount to each.
I also avoid services that are monetized by ads elsewhere and pay for Kagi to get ad-free search. I will avoid all services that offer free tiers with ads and paid tiers without ads as I just fundamentally do not believe that the business model can work at scale without causing harm.
I also host my own email as I do not believe that it is possible to provide free email to people without somehow also doing things with their data or attention that goes against their interests.
