Some people on the Blenderio telegram claimed they have received the refund:

https://t.me/c/1441579769/1129, but then they announce the service got hacked.
I suppose it might be bad crisis management. Not to mention they are being reliable for people's money, and how awful the situation might be for the team. So I think the questionable announcements are reasonable. Although they indeed should perform better, as JeromeTash said, I do think they better to clarify the incident first. But maybe the team just wants a quick way to assure user funds safe.
But yea, with such kind of announcement its kinda seems like a phishing scenario, mentioning the probability their account might be hacked as you said it.
