I wonder what would happen if there would be more "Karens", that would complain about this?

Looking at the screenshot, let's say it's a cat food ad... if that "Karen" would call the cat food company and complain that their ad wasted her time with an old relative, or whatever, and in turn waste that companies time... and multiply that with 10.000 karens,... but it needs people to actually be proactive about stuff like that.
