Is there an ethical conflict with using a closed source platform for supporting an open source project? Namely, AskUbuntu is part of StackExchange and I went looking for the StackExchange source code. I didn't find it. By the way, I did find some clones.
Now, personally, I don't much care either direction and always recommend that people use what works for them. Just because I use open source doesn't mean that others must do so. I've never been much of a zealot.
Anyhow, I realize this seems like an opinion question and, indeed, I'm also interested in opinions. However, I am kind of wondering if there is an "official" statement concerning the use of closed source where this site is concerned? Additionally, I understand, from my reading, that there's a bit of a special relationship betwixt the two companies.
So, no, I'm not just wanting opinions (those are welcome, if allowed) but I'm actually wondering if there's an official policy or public statement concerning this. I can not seem to find it nor am I seeing any answers here on this site.
