I think what you don't understand out of this is that 100's of 1000's of people use springtomize 3. ^^More than 10's of 1000s
That number doesn't seem right either & When S3 was first released it had a bunch of bugs. People probably downloaded it from other sources just to make sure it would work for them. Not condoning that but thats probably where that 90% has come in.
