I installed and activated the plugin to take a look at the advertising and on a wide screen monitor, it's not that bad. The images are pretty big but the advertising is for related plugins and services the company offers.

I don't see a problem with that. MonsterInsights which I reviewed a few weeks ago does the same exact thing. If a plugin is going to advertise something, its settings page is the place to do it. Advertising outside of this area is a big no no for me.
