The changes have been committed and pushed to a branch of the main (Apache-licensed) repo, with the clear intention of eventually being merged into the main branch. So it’s hard to argue the code isn’t published under the same licence as everything else. Still, I think they should have created their own website.
I'll just quote Oleg, who was an Organic Maps contributor working on the new website (amongst other things) and is in the CoMaps team now:
"The original design was created by me. I also personally hired and paid for a designer to also work on the design. Later I hired a developer and paid him myself to develop the website. Recently minor updates were made, for example removing the stock photos from the Community page, which was paid by OM. This was from the beginning through today open source under the Apache license."
