Yes. That sentence is setup for the speculation in the third paragraph. Folks in this sub-thread are wondering how the one-time price option plays out with Apple Creator Studio.
If you look at Office 365, OneDrive, Teams, SharePoint and Exchange Online as well as AI services and coauthoring are not included in the one time purchase price, as these require ongoing infrastructure supplied by Microsoft.
If you look at Adobe Creative Cloud, you see cloud storage and cloud libraries for maintaining files and assets and sharing them for collaboration, Behance, asset licensing such as Adobe Fonts, and generative AI tooling, as well as a pile of additional apps which were never sold separately. There's also tutorials to help you learn that smattering of apps and plugins.
Apple Creator Studio is a service, so there will likely be at least some product development going to create exclusive functionality - likely in the form of new apps which cannot be bought separately, content packs, AI integrations, additional collaboration features relying on hosted infrastructure, and so on. Since a lot of the storage features and base collaboration are instead part of the iCloud infrastructure, that last point may be a tricky line to walk though.
