It's not because I want something that I actually need something. I've wanted to build a UPS with lithium batteries for a while, my ads are all BMS, lithium cells, etc... This is definitely good for advertiser, but as one of the "people", all I see are hard-to-resist ads.

AliExpress is especially good at this for maker gear, I'll look at a reflow station and they will spend the next 6 months showing me reflow station ads until I cave and buy it, even though it is a purely frivolous purchase.

Personalized ads are extremely effective when your profile is good, but that does not mean that I don't see it as a bad thing.

I think personalized ads are way worse, because they entice you to buy products you actually want. Buying things is usually a bad idea, so personalized ads make this problem worse.

Value to whom? Certainly not to me.
