Yes, but I see people getting confused that the original bitcoin wallet is bitcoin.com or blockchain.com. Because this is what google returns to them. I agree with the decentralisation, but it isn't centralized if the bitcoin developers made the wallet. It wouldn't be closed source neither.
Unfortunately declaring a wallet "official" is not going to change that. Someone just heading towards the first site that looks appealing won't bother looking for an "official" label either.
At least in my Google search results Bitcoin.org tops the other sites, so at least that's something. Also Bitcoin's wikipedia page only references Bitcoin.org and not that other site, presumably because as far as Bitcoin is concerned there's nothing noteworthy about Bitcoin.com to begin with.
