(This is written as a thought exercise) Should it actually be anti-trust to bundle various office applications together? Are they actually related enough that they can only be sold as a bundle? Or have we just gotten used to the concept of an Office Suite that we can no longer imagine them as separate pieces of software? Technically you can still purchase the Microsoft Office applications individually, though I doubt that anyone does. Would anyone actually mix and match word processors, spreadsheets, presentation software from different vendors? You cannot buy or use Google Office applications individually though, as it's only available online through an account that you need to setup. This is where the main question of this anti-trust and anti-competative behaviour comes in - how far can a company go in bundling products together? Currently Microsoft (and let's not forget Google) are bundling together more or less a collection of: Word Processor, Spreadsheet, Presentation, Email Client, Database, Diagramming, Note Taking, ToDo List, File Sharing, Chat Communications, Video Communications, Project Planning, File Storage, Desktop Publishing, Data Visualisation, and more. How much further can this bundling go? Would we have a world where you spin up a Microsoft Office which includes access passes, coffee, payment processing, accounting, etc? Where would be the line between using an Office Suite and where would be the line for other companies to provide products and services?
