It was actually nothing that was said by PSPP devs, but in the GNU documentation. Specifically, this:
I actually do get the sense that the devs here care about the Windows experience, but just don't have the resources to test it. It's also been noted that all the devs use some Linux-based OS exclusively, and because open source projects naturally are motivated by personal priorities, there is an underlying tendency to notice and fix things in Linux first.
I don't actually have a problem with things being Linux-first, by the way, and I think most of the good open source things out there often are Linux first, and then evolve into more mainstream things (e.g., GIMP, OpenOffice). I personally think for PSPP in its current stage, being Linux-first is *good*, as long as the Windows option is kept around and paid attention to (as it obviously is).
My comment before was just in the context of the fact that the discussion around how to fix the messaging was primarily around a Windows-specific situation, which maybe didn't apply to PSPP on other platforms. I do think it's better to focus energy on improving PSPP for all platforms and not spend too much time on just this one issue.
By the way, I'm not yet a frequent user of PSPP myself, as I'm "waiting in the wings" for it to have enough of the features from SPSS that I need to be able to switch over (specifically, I do a lot of repeated measures studies, or mixed designs with between and within subjects factors, and the GLM in PSPP doesn't yet support that). I really am looking forward to the day that I can switch, though. I really hate the SPSS pricing model.
