What exactly are the preservation concerns for open source standards expressed by Massachusetts state supervisor of public records, Alan Cote?

Are any of them legitimate concerns?

from ZDNet:

"The rigid policy, such as the initiative before you that excludes any vendor or any process and relies on questionable, untested and unreliable practices or tools, does not suit the commonwealth well," Cote said in prepared remarks. "It may very well result in many electronic records being lost or destroyed."

Cote added that the state's records management system renders what format a document is saved in as moot.
