I think the only way to get the no-Copilot version now is to already have the Copilot version and try to cancel your subscription, and only then they'll offer the "Classic" version sans Copilot as a last ditch retention effort. If users actually wanted this stuff they wouldn't need to bury the option to not pay for it.
australia recently sued microsoft over this.. saying they had to increase their prices but not mentioning that they could downgrade to a 'classic' subscription. totally misleading under australian consumer law.
