Both really. They stopped individual copies as a cost cutting measure, then got rid of the support people who updated/checked it (and the process), then had someone rewrite in 'simplified form' and throw away 30 years of development, presenting the new version as a fait-accompli. MATS needed updating to embrace the totally new computer system (ala NERC), but the result was a disaster. Now money being wasted to fix a problem that should never have arisen.
