Sure. The owner of a domain can do whatever they want with it. Still, for us the scenario is as sketched above, and it is not a good look.
I was in contact with Christine at the time, and first she felt comfortable to transfer the domain to me for use with SocialHub, after which I started a bunch of forum threads and set the “Fediverse Development Portal” header you still see at the top. Later Christine mentioned she preferred doing an update of DNS rather than ownership transfer.
The reason I do not @-mention Christine here, is because she isn’t following the AS/AP space anymore. She only wants the best for her domain. That may be a portal under SocialHub or SocialCG, given that the initiative here didn’t find uptake of volunteers.
But it does not change anything to the decision-making went, and no one thought of informing the folks here at SocialHub, that runs at a subdomain of that portal (!). And I find that very weird, to say the least.
