If you are against them on a moral basis then use another service, I imagine that has a more negative impact on them.
If you just want no ads, pay for it.
I hate ads as much as the next guy and use a variety of blockers but i'll pay for any service with a reasonable payment method.
The price of food items has gone almost 50% up during last year, the wages are not keeping up with inflation, and I already pay for utilities and internet. I ain't paying shiiiiiiiit.
Okay, so this actually has nothing to do with how YouTube "demonitizes content creators, while protecting doxxers and content thieves". It's actually just about you not wanting to pay for it.
Odysee is pretty alright, maybe nebula? I haven't used either a significant amount so i couldn't give out recommendations. I personally doubt they are as good as YT though.
