Not all roses for SMBs
Having had first-hand experience with this, I can vouch that most SMBs do not want to dedicate their IT time to deploy Copilot on M365 in a safe and sensible manner.
It is far more involved, requires re-thinking your data storage, labeling and correct permission setup to work as intended - and ONLY as intended.
On top of that, Copilot is still very much under development and it's hard to rely on in anything business-critical.
