Customer Guidance for Reported Zero-day Vulnerabilities in Microsoft Exchange Server

I dont understand how all accounts have access to run remote powershell on Exchange.  Reading this:

https://learn.microsoft.com/en-us/powershell/exchange/control-remote-powershell-access-to-exchange-servers?view=exchange-ps&viewFallbackFrom=exchange-ps%22%20%5Cl%20%22use-the-exchange-management-shell-to-enable-or-disable-remote-powershell-access-for-a-user

Under "What do you need to know before you begin?"  third bullet states:

"By default, all user accounts have access to remote PowerShell. However, to actually use remote PowerShell to connect to an Exchange server, the user needs to be a member of a management role group, or be directly assigned a management role that enables the user to run Exchange cmdlets"

I don't understand how users have access to run remote powershell commands on Exchange with the above information.  Can this be explained?
