Thoughts
I’m firmly in the lowercase “into” camp. I think they decided on the wrong way.
They decided on following the capitalization of official media, but no other Wikipedia page follows “official” portrayal over rules of grammar. See, e.g. the Wikipedia page of any band or company that stylized their own name in all lowercase.
But like, I’m sure there’s a reason that they decided the way they did and I haven’t read the 40,000 word argument or the Wikipedia style guide or anything.
