That is not my experience. The mods there close any question that's been asked before even if the previous one is out of date and is closed to new answers. They also just seem to close most questions period.
Are you sure you're not thinking about Stack Overflow? I hate defending reddit ever since the API debacle, but there are scads of subreddits, many with different sets of mods, and all of the ones that help me with product reviews don't seem to have aggressive moderation?
Edit: for example, I was searching for woodworking design software this morning and got a lot of helpful-looking results from reddit.
