But SharePoint is the linchpin for Microsoft 365. Well technically SharePoint and Exchange. You can’t use any Microsoft 365 products without SharePoint.
OneDrive uses SharePoint. Outlook Groups and Teams Channels create Microsoft 365 Groups. Every Microsoft 365 Group creates a SharePoint site. Microsoft Loop uses Microsoft SharePoint Embedded.
SharePoint is now a “file and document management system suitable for use in any application”.
So, if you want an alternative to SharePoint you would need an alternative to any M365 Product, including Outlook and OneDrive.
Fun Fact: Teams messages are actually stored via Exchange Mailboxes.
