I see two major differences to the mass advertising of yesteryear (which, similar to you, I have also lived through):
1) The psychological manipulation inherent to all advertising has shifted from diluted, mass manipulation to pinpoint-accurate, targeted manipulation right down to the individual level, with impunity via plausible deniability.
2) Advertising is a major distributor of malware, with the ability to target anything with a chip.
Given either one of the above, I absolutely cannot trust any advertising delivered via modern technology. Since we have to contend with both issues, I view modern advertising as one of greatest threats to my mental health and individual sovereignty that exists in my day-to-day life.
