Why would Microsoft remove the beautiful Aero Glass effect and replace it with flat colors and cheesy translucency?

No Aero Glass is an absolute deal breaker for me.  There is no way I'm installing those ugly flat windows on my desktop.  The transparency that is there which lacks blurring is an ugly joke.  On a scale from one to ten of how upset I am over this... I'm like 1000000000 seriously considering buying a Mac out of pure out-of-my-mind crazy spite.  I cannot even express in words how upset I am over this.  There is absolutely zero chance that I will ever install Windows 8 or Blue or any another Windows operating system onto my computer until Aero Glass is returned or something more beautiful is included.

I am not developing a single app for Windows until Glass is added back.  For my next phone... I was considering Windows Phone 8.  I even stopped by and played with one at Verizon the other day.  No glass?  I'm not wasting my time looking for mods.  Windows Blue is going to be very sad, because I am ditching Windows permanently if glass is not added back, like now, like before I have to spend a single additional second trying to find workarounds on the internet.  Yep.  I can feel an Android Phone in my future, and a sudden love for Java, which I currently hate, coming on.  Feels like the incredible .NET is being abandoned too.  Guess I better go submit my resume to Google.
