Maemo is sufficiently CLOSED in enough parts that 3rd parties couldn't use it on other devices and make it their own, Hence little to no adoption.

Android "Source Code Available for Android 4.3
Android is an open-source software stack for a wide array of mobile devices with different form factors. .... We wanted to make sure there was no central point of failure so no industry player can restrict or control the innovations of any other. That's why we created Android and made its source code open." Hence large scale adoption.

Not a failure of management or of the technology, just a fundamental missunderstanding of why OPEN is winning.
