I totally agree, and I never understood how adding a parasitic middle-man is supposed to make things cheaper.
"without it, we would have to pay out of pocket for ad supported services!"
Actually, I don't think we would for a lot of things. The internet existed long before it was advertising funded. Web-pages used to be things that people made because they were passionate about what they put on those pages. Advertising only came later.
Hell, there are still plenty of things that people build and maintain because they like it, not because they make money from it. How many people work for free on things like Wikipedia, FOSS, Fediverse, etc. just because they want to see it succeed?
But the Democrats aren't going to start fighting for what the people want if voters keep voting Blue No Matter Who. We've seen them continuously run to the right, because they don't feel like they have to earn votes.
I get what your saying, and I think there's some truth to it, but I've also seen the Democrats in action, and I can't say that I have any hope that they are going to suddenly change their ways. If they really don't want the 3rd parties to split the vote, then they should try adopting the policies that the 3rd parties are running on.
