You could make names optional. I'd guess that some useful data could be gained if the analysis is done matching survey results with user data.
Is MB understood by respondents to be separate from Picard?
Or does MB cover both?
Prior IT skill level would seem a major predictor of user satisfaction, especially MB database, Picard a bit less so.. And number of edits contributed. A question about prior IT skill level could confirm or discount this. And help quantify the likely benefits, if any, from a far easier UI.
