Using Airtable sync to make useful data available to all?

Has anyone made sync tables available to all? Like ‘calendars of interest’ in Google Calendar. All sorts of reference data could be pulled into an Airtable base via sync instead of maintaining locally.

I haven’t come across any platform or marketplace to browse such tables. Are there any? I guess individual providers could make their own tables available if they chose to. Are there any?

I’m sure someone has already thought about all this.
