The source looks very very real. You have the website the and twitter links, advise / works with Qualcomm in this very field. If he says people notating his organisation and are looking to bai,l it must be because they feel the end near. No one waits to be told they need to look work as company has been sold.
1,) they know it's possibly being sold, they may get laid off 2,) for some reason, he has fielded many calls recently
So something is going on. Though I am insure employees would be last to know, they would get a feel for how things are going.
