I think it needs repeating every time this discussion comes up: the discussion isn't about ads, it's about "bad" ads (tracking, trading PII, ads with malware...). The group that is against ads including images on the sides of buses (basically the argument is usually something along the lines of that it encourages unnecessary consumption or similar) is so small as to be irrelevant. You should consider "ads" in the context of this discussion to be "bad ads", where the limit for what constitutes "bad" is of course different from person to person, but for the sae of discussion assume it is "bad enough".
