Besides, having a publisher doesn't mean you're no longer independent in development. Think of publishers of books. The author can be completely freely creative if they're famous enough.
Publishers help with advertisements, localization, support the devs on multiple platforms etc...
Book publishers and game publishers are not the same. A traditional game publisher finances the game development. In fact the publisher owns the game, having almost 100% control over the project.
Everything else is not video game publishing in the traditional sense.
