I'd go on further, we cannot have advertising as a business model, targeted or not. It worked previously, classic Google was a good example, but mixed with shareholders, it doesn't work, incentives screw up any attempt of providing a better product, because the product become the ad space.

Throwing Musk in there is strange. To my knowledge he doesn't really profit of ads, X probably have ad revenue, but that's not really his business model. Tesla stock however, that's a completely different addiction, mostly not relevant to consumers, but that stuff is immune to any type of common sense and traders can't seem to get enough of it.
