Everything that makes advertisers happy is to the detriment of humanity as a whole. Everything that makes advertisers’ jobs easier also makes it easier for authoritarian governments. “Innovation” is no longer about creating new things, it’s about taking what already works, breaking it, shoving ads on it and charging a ransom in the form of a premium subscription.
On the other hand, there are endless ad-skipping tools, pages and sites where the main attraction is the lack of ads without a subscription. More and more people are talking about how intrusive and annoying ads are, even those who make their living from them. As the efforts of big tech to please advertisers grow, so do the efforts of ordinary people to screw them.
Very Cyberpunk.
Advertising as a concept is not bad. But given the realities of capitalism, the greedy executive and shareholders can never resist the easy money. As a result anything that implements ads will eventually be completely overrun and ruined by them. Might take a year, might take 10, but once that door is opened it is inevitable.
