Inherently evil and annoying? No, but in practice it's annoying and online at least, potentially problematic on other levels as well such as security and performance. Telemarketing isn't inherently evil and annoying either, but it's become a playground for scammers with robocalls and constantly shifting spoofed numbers. That, maybe, should tell you something about the nature of the medium, or at least the nature of the medium when it's being exploited by a broad population.

I think telemarketing is annoying, it's also intrusive and requires effort on my part. Passive advertisement on the internet does not.

Note I am not saying there are not annoying advertisements, but that's an issue of implementation, not the concept of targeted advertising. If anything, Google would know I will never click on an annoying ad if they "invaded my privacy" more than they do now.
