If the Rails Foundation tried to take Rails from its maintainers, I would stand up for the maintainers, despite my political differences.
Rails is not owned by the Rails Foundation in the same way RubyGems projects were not owned by Ruby Central.
And neither are legitimately owned by Ruby Core.

I’ve used this a bit today and my god it’s so good to be able to quickly see the shape of a method just by looking at it. The documentation factor alone is *huge*, let alone the other benefits.
