The healing will be when all ads and marketing will be down to zero. This companies like Facebook and Google make their billions putting on your face what you don't want or need and someone else pays them good money for that.
You may think it's too radical but we must make marketing illegal. Then fix the web.
I've given some thought to this, and outright banning marketing sounds basically impossible. Not just from a "good luck getting that bill passed" sense, but in a practical one. Where do you draw the line on "marketing"? Presumably my writing a glowing review of a product I like won't be banned, and online banner ads will. I'm not trying to make a "the line is blurry therefore no regulation can happen" argument, rather I think "marketing" isn't really the right line. Specifically, what ought to be banned is the sale of attention. Anything where money or favors are changing hands in order to direct attention intentionally to your product, service, etc. So you can absolutely have a marketing page extolling the virtues of your brand. You cannot pay to have that page shoved in front of people's eyeballs.
Yes, I know that this kills the ad-based funding of the current internet. Let it burn. A mix of community-run free services and commercial paid services is infinitely preferable to the "free" trash we've grown dependent on.
To make an ethical argument: quantifying and selling human attention is gross anyway. Some things just don't belong on a market.
