Microsoft has rebranded its long-standing Office suite as the Microsoft 365 Copilot app, a move first announced over a year ago but only recently gaining widespread attention on social media.

• The rebranding is a "forced" pivot for Microsoft, pushing AI integration despite user “pushback.”
• Microsoft has invested approximately $13.75 billion into OpenAI since 2019, now holding a 27% stake valued at $135 billion.
• The name change is seen as a "high-stakes survival strategy" to tie Microsoft's stable revenue to its most speculative AI venture.
