It seems like you’re right, but it’s strange that the data world seems to be moving in the opposite direction, with PaaS products like Snowflake, DataBricks, Microsoft Fabric, even Salesforce’s own Data Cloud eating the world.
PaaS has always been this thing that isn't pure infrastructure or pure hosted software that you use as-is. Salesforce has something over 100K attendees of partners and users to its annual conference. It's always been this in-between thing with a fairly loose definition. I'd argue that Salesforce was long a cross between SaaS (for the users) and PaaS (for developers). You can probably apply the same view to a lot of other company products.
