DoorDash has told employees not to send or accept LinkedIn connection requests from Instacart staff, even with prior relationships, while its $17 billion acquisition awaits approval. The rule, part of an internal Q&A filed with the SEC, aims to prevent antitrust 'gun-jumping' before the deal closes. With closing expected by late 2027 or early 2028, the DoorDash-Instacart LinkedIn freeze could last up to 20 months.
