the actual title on the link is "Postbox has been acquired by eM Client!" which is different enough to "After 16 years of development, Postbox Inc. is winding down its operations" that I think it should be changed.
Not the exact same title as on the announcement on the Postbox website, but far more accurate - and relatable. Maybe they used different drafts of the announcement text?
I think the difference in wording is telling. You would expect "After 16 years of development, Postbox Inc. is winding down its operations" on the Postbox Blog and "Postbox has been acquired by eM Client" on the eM Client website. But it’s vice versa.
"Postbox is winding down its operations after being acquired by eM Client"
