If ad companies would be paid according to customer conversion rate instead of how many ads they spam everywhere, it would collapse within a financial quarter.

Thinking that people support a brand or product that constantly annoys them is next-level stupid, but it's their main strategy. Google's conversion rate is less than 4% and instead of realizing that spamming trillions of ads on every site is causing that abysmal rate, they double down and get off to bigger "reach".

Also, Google lied to customers of their TrueView ads and just presented people muted autoplay ads instead. Here's an analysis about that.

tl;dr the only one benefitting from ads is Google.

As aptly explained by writer Cory Doctorow:

Here is how platforms die: First, they are good to their users; then they abuse their users to make things better for their business customers; finally, they abuse those business customers to claw back all the value for themselves. Then, they die.
