I'd say that Golden might be the most interesting competitor to Wikipedia I've seen in a while (which really doesn't mean that much, it's just the others have been really terrible).
This one also has a few red flags:
- closed source, as far as I can tell
- aiming for ten billion topics in their first announcement, but lacking an article on Germany
- obviously not understanding what the point of notability policies are, and no, it is not about server space
They also have a features that, if they work, should be looked at and copied by Wikipedia - such as the editing assistants and some of the social features that are built-in into the platform.
- they will make a splash or two, and have corresponding news cycles to it
- they will, at some point, make an effort to import or transclude Wikipedia content
- they will never make a dent in Wikipedia readership, and will say that they wouldn't want to anyway because they love Wikipedia (which I believe)
- they will make a press release of donating all their content to Wikipedia (even though that's already possible thanks to their license)
- and then, being a for-profit company, they will pivot to something else within a year or two.
