NBC isn’t the one who would be doing the manipulation. He would simply be the means for a supposedly-10-year-old problem to all of a sudden come to light.
How many complaints has Xerox gotten on this issue in the past 10 years? As David Kriesel said, these errors could be deadly. These machines are common enough that if they had been doing these things for the past 10 years there would be numerous audits that should have failed but didn’t, numerous blueprints that shouldn’t have worked to build real live, safe bridges, buildings, etc.... yet they did. Etc.
This started out being something that only happens when you use the low-quality settings. Then when the questions came up as to why they used low-quality settings to copy the long-form, the phenomena suddenly became much more widespread, including (eventually) even the default and higher-quality settings so that on those machines these errors should have been happening ALL THE TIME. For the last 10 years. Yet the 6’s and 9’s on Obama’s long-form are not substituted, and Xerox has received how many complaints on this in the last 10 years? These phenomena are supposedly so common - and yet Kriesel was so surprised that he thought somebody was playing a joke on him when somebody said the copies he made had errors.
NBC hasn’t claimed to have replicated number substitution.
He has reported a workflow that replicates numerous anomalies that Zullo’s experts claimed couldn’t be replicated. The anomalies are explained by long-standing MRC processes, so no speculation or conspiracy is needed to explain them that I can see.
At the link below are what NBC is claiming to be his “confirmation documents” and itemization of the anomalies/features that replicate ones in the WH LFBC pdf:
