No. If you are actively searching for something, and go to a specific place that sells that thing. It is not advertising, the active party is you not them.
The problem is when the active party is the ad-networks, the trackers, the junk pushers.
If I go to a review site, for say lawn mowers, and they say hey brand 1 is great, but brand 2 is better because of ‘reasons’; I am active, engaging in the process. If however, I then go to a site that is about tigers, and brand 3 pushes their ad to intrude on the tiger info…this (in my opinion) is a major intrusion into my private space.
Television ads are a grey area, they don’t tend to track you and follow you around in a creepy way.
Sponsored content, is in my opinion very similar to TV ads, the sponsor is the same for all viewer of the vid in a similar way to TV.
