In an ideal world, releasing the bitcoincore code on bitcoin.org or sdfsdfsdfsd.io shouldn't make a difference for bitcoin... but it does.
We haven't seen it tested so there's no way of knowing. I'd say a fully Ver-ified .org would be misleading and unhelpful but wouldn't have much effect in the great scheme of things. The main thing it would do is enrage newbies and turn them against what he's attempting to push.
Bitcoin.com is a significant property too. BCH is still in the toilet price and penetration wise compared to the past. You can have an initial effect with things like that but it won't sustain if it's empty.
