Maybe.
Maybe not.
The report doesn't state pilot stupidity as a cause (or 'contributing factor').
I haven't met too many pilots that I'd consider stupid.
A decision might look stupid in hindsight, but wouldn't it be more helpful if more energy were focussed on investigating what causes otherwise competent and intelligent people to make a decision that seemed to them to be a good decision at the time?
If the implicit message in all these kinds of reports is "stupid pilot", why bother investigating the accident?
