When Will They Learn?

Recently when Windows Live Writer Beta got realeased, I signed up with Microsoft Live Spaces to give it a test drive. I thought that by now Microsoft would have learned from their past mistakes, but boy was I wrong? The very first thing I noticed on Live Spaces was a huge ad banner across the top of my live space home page. I thought I would be able to customize my space and either get rid of it, or move it to the bottom where it's less distracting. Sure enough I can remove the banner, but only if I sign up for MSN Premium (read $$$). Haven't they already learnt from loosing the search engine battle to Google that distracting forced advertising do not work?
