No?

Perhaps:

[(dev time of maintaining comments)
+ (risk of outdated comments causing bugs * dev time of fixing resulting bugs)]
<<
[(dev time gained by more contributors each being more knowledgable)
 + (reduced time from contributors trying to figure out the code)
+ (risk of misunderstandings causing bugs that could be avoided by better comments
    * dev time of fixing resulting bugs)]

(Though perhaps the 2 clauses I added could be viewed as variants
by the original one.)

How did you reach such a conclusion? Do you have any data points to
support that?

It seems plausible.  I doubt we have any data points to support the
opposite conclusion.  Given that, I would suggest it is better for an
open-source project to err on the side of more public information
(i.e. openness) rather than less.
