I don't get what the alternative is supposed to be. You can't make stuff like blockbuster quality movies on ads and/or donations alone. And between ads vs subscriptions, ads are iffy because you end up with sketchy or unethical advertisements. Plus ad blockers make it hard to sustain a business on just ads.
In an ideal world, nobody would need to "make a living" and we'd be able to offer more services for free. But we don't have that ideal world. Musicians, animators, writers, programmers and more all need to get paid somehow.
It's admittedly annoying how fractured subscriptions get, though. I miss when Netflix was the only streaming video subscription I needed. Now there's half a dozen major services and they all want exclusive contracts to show certain movies and TV.
Personally, I'm happy to pay for the stuff I use a lot. Which includes stuff that I don't even have to pay for (eg, I donated $20 to kbin). It does suck for stuff I only want a little of, though. eg, I don't have any news subscriptions because I only check news sites here and there and it's almost never the same site, too (mostly I get linked from sites like this). I want to see subscriptions become a bit more centralized, spanning multiple sites to account for this.
