I completely agree, though I haven't been thinking in terms of the cancer metaphor myself. I have been thinking a bit about how we could limit the negative effects of both advertising and other phenomena like social media algorithms:

1. Almost all advertising is based on manipulation of human cognitive biases. There is a limited set of biases, and the mechanisms by which they can be exploited are both limited and easily detected – we can most likely train AI to do it. Therefore, it's possible to start thinking seriously about making laws that ban corporations and organisations from creating marketing that exploits these cognitive biases.

2. When it comes to social media platforms, there are two routes we could go down. Either we could regulate their algorithms the same way – or we could force social media platforms to both make their recommendation algorithms open source, and to open up their platforms to third-party recommendation algorithms that people can choose to use instead. This would be like a recommendation algorithm app store that the company has to provide to their users. You might want to select a youtube recommendation algorithm that optimises for personal development – or a facebook feed that optimises for creating real-world connections

Of course corporations would fight this kind of legislation with tooth and claw, but that's how it is. I would be happy to get some thoughtful feedback on these ideas, their technical and legal plausibility, and any potential negative unintended consequences or loopholes that could undermine them
