Dear web content, social media, e-commerce and other fledgling e-companies, and Amazon:
If I value your service, I prefer to pay a subscription fee than be served up advertising in any form, including email. My most precious commodity is my time and I'll go to great lengths to protect it. If I don't value you service, I simply won't use it. And I'm not alone.
Same thing applies to lousy UI design, I'd rather pay for a more efficient experience than navigate around what you think I ought to see.
