I think as a child I got viruses from one of the ads, you know, the ones would put on the side of the site. We had to call in a guy, to clean parents’ computer. I felt really guilty and never touched those ads again.
So Google’s and Meta’s main business are ads. And recently I felt confused. Do people click on ads? Don’t these ads feel phishy to them?
If you use Firefox for Android you can install ublock. Also there are third party YouTube apps without ads.
