The salesman popping in once seems better to me than the neighbor who always shows up whenever you're discussing Football to say all the ways Soccer* is better (every... single... time) . But at least we can block the neighbor equivalent on here, can't do that to the person you don't know yet.
* Or insert Football and American Football as appropriate.

I don't see that comparison at all. An annoying neighbor is one thing. They can be annoying for any number of reasons. I guess for me any and all salespeople cold calling me on the phone or at the door or even in the forums is a real turn off and I don't care what they're selling.
There are plenty of publishers and creative types here. I welcome their RPG product material
So do I! When they are a part of the community, sharing ideas, participating in conversations, and so on in a genuine way. Then if they announce their products in a thread, I know who they are and what they are like and can check it out. But as I said in my post, when someone shows up for the first time (and only time) to just shill the thing they've made they demonstrate seeing the community as nothing but potential consumers. Maybe in our culture today people are used to that, but I don't think I'll ever be.
