Not to mention that platforms are having a free rein over gathering sensitive information and turning it over to advertisers so that they can 'target' people as they please ...
This suggests that there's a huge void in the market for websites and magazines who would go the length to curate their advertisements to make them relevant and not annoying.
there is, but the push for the network-based advertising is too strong, because in addition to mere advertising it also delivers market insight, which is arguably more valuable
Typically web doesnt have the same kind of control and advertisers have more or less free rein to do what they want.
