Proprietary sw: easy to use/maintain, fun, works most of the time, professional developers behind it, profit.

Open source sw these days: several versions, constant tweaking, works so-so (depends on the software), semi-professional developers working on it (I am not saying they're not good) or amateurs (with amateur designs), not for profit, of course. EDIT: remove double 'multiple versions'.

Proprietary sw: once discontinued for one reason or another, you're pretty much fucked up

OSS: You can still manage to sorta make it work

I guess my point is, if the software GP talked about was proprietary, he wouldn't have known what was wrong in the first place.
