It has been interesting watching the various end runs around third party cookies and data collection constraints.
Trivia Note: Lou Montulli invented both the HTTP cookie and the blink element. Ah, the days when I thought blink the ultimate of page cool :)
It is sad that, so often, egregious is necessary threshold to change. And the initial reaction solution a reciprocal pita.
An interesting, if too often depressing, experiment is to click on a site and note when eg before/after cookie authorisation a cookie is set, if there is actually a difference in cookie set between authorisation settings granted...
