> If I pay someone to print flyers is that advertising?
What the hell, we're talking about internet... you can't put printed flyers on the internet.
> If I pay squarespace for my site, is that advertising?
No. It's your site, not a third-party site promoting your site!
> What if I need a Google maps subscription to place pins? Is placing a pin then advertising?
If you promote it somehow, yes... if you just say there's a business there, no, since you're not actively promoting it. Information that something exists by itself cannot be included in "promotion".
> And all existing videos with sponsorship need yo be removed?
Yes, or re-uploaded without the sponsor segment.
> And I guess no online watching of sports (lots of people paid to wear a logo there...)
There could be exceptions for ads placed on the real world which are not paid for by the site/creator. There's always cases that must be allowed, no prohibition is absolute.
> Presumably no product placement in Netflix shows (not sure what to do with old content?)
To be honest, I wouldn't mind subtle product placements in shows. That's a lot less hostile than actual ads we see today on the Internet.
> Of course I'm not paid to advertise MiraclePill.
If you lie that you're not paid by someone while you are, like with any law, you can be prosecuted for it.
> Alas, I fear it isn't...
You didn't show what you think you did.
