There was plenty of free content online before ads, in fact I claim that the web was better before ads arrived, and it is getting worse by the day. Marketeers ruined it.
It happens over and over. YouTube had plenty of great content for free before monetization. Now it is becoming worse by the day, because everything is ad-related. "Influencers", etc.
> Consider how much better the world has become due to easy access to information. To yank that away seems like bringing a dark age.
Easy access to information is a consequence of the Internet and then the Web, both technologies having been developed by government-funded programs, respectively in the US and in the EU.
Ads brought us re-centraliztion, targeting and erosion of democracy through extreme polarization and fake news.
I know this is hard to believe for a lot of people here, but human beings are motivated by many things other than monetary profit.
