I think I can hear Google managers saying for themselves: ‘Want to add some interactive bells-and-whistles to your site? No problem! Just make sure your site is attractive enough, so it makes people come to you, and by extension, to us. Your success is ours, as well.’
Restricting things and putting artificial limits on what one can do, is a sure tell-tale sign when service provider is going slowly, but surely, down. It starts in fear of competition, or greed at peak of monopoly. But then it blocks your own creative forces, because you’re draining yourself working more and more, with less and less results. And it blocks people which provide content, because they’re not able to use existing solutions, services or take advantage of their own work. Dull looking, non-interactive site, without ability to collect advertisers money is next to dead duck. And it doesn’t take a genius to see why.
