Let me suggest you are not thinking straight. Advertising, like it or not, is what keeps the internet alive. Without this revenue stream it would collapse. The internet doesn't run on idealism, it runs on money. Before making statements like that go start a non-trivial internet-based based business and gain some understanding.
I think what crowdfunding has been showing us is that we have gone through a dark ages of internet business models (ads), in that the ease of marketing through ads blindsided people to pursuing more creative (and yes, often more laborious) business models.
I disagree ads are what keeps the internet alive. What keeps it alive are hackers and artists. They share this: an itch to create. They will create even for free. But we would have been so much ahead in creative business models that they could explore (see Kickstarter) in an alternate reality where ads did not exist.
Unreality. You can't run a business on Kickstarter money. It's a kick start. After that you need money from somewhere. Or do you expect people to eat bits?
If you are going to create an internet-based business that will support more than a few people (both users and employees with their families) you need money. Lots of it.
The user side is simple: As the user base grows your infrastructure requirements grow as well. And, at certain milestones these needs grow in large capex bursts. Flexible services such as AWS have made scaling far cheaper, more linear and less expensive, but it it still very expensive once you cross certain business-dependent thresholds. Hardware is hardware, whether you own it or not.
Of course, the team will scale based on other parameters. More engineers, more designers, customer service, accounting, operations, whatever. More people. Not working for peanuts of feel good hippie thoughts but for money. They need it to live, rent or buy a place to live, feed themselves and their families, save, invest, have fun, etc.
Given that internet culture quickly --from the very early days-- levitated to free and add-supported free most internet users only want to pay for their connectivity. Nobody wants to pay for anything on the internet. That's just a fact. Pick any service, say LinkeIn, far more free users than paid users. It's like that across the board.
Hell, it's even like that in mobile. Unless you get lucky it's nearly impossible to make money with paid apps. Make them free and then sell them something from within the app or support it with ads.
I stand by my original sentiment: The internet would collapse tomorrow if advertising was banned. That doesn't mean I prefer it that way. I am simply reflecting reality.
While I don't necessarily agree with the grandparent post, we should think back to the early days (in the early '90s) before the Net's full-scale commercialisation. It was a different Internet, much smaller and more uneven, but not necessarily a worse one. People paid for their own web hosting or used space provided by educational institutions/government.
The Internet didn't always run on big business - business gradually shaped it into the way it is today.
