It is, however, delusional to think that at this point anything can become a viable alternative to Wikipedia, unless Wikimedia collapses because of reasons from within.
But having an open data project full of information that's actively contributed to and fact checked, with copies over many servers, is much better than having the same thing but fragmented. I still don't see a reason. If it was something else or corporate driven, I wouldn't bat an eye. But Wikipedia?
