Sometimes you should have the choice of making a slow web site that doesn't fit on the phone screen. A large corporation shouldn't dictate how you present your information.
Sometimes you want to put a document on the web without having to pay someone to run on Google's treadmill of changing standards and policies for the rest of your life.
I'll take a crappy-looking web site with good content over an SEO-pumped disaster that provided no information.
Craigslist, eBay, and dozens of others didn't get to be huge because of their good looks.
