What is needed is a solution to how the G Suite alternative (presumably open source) will be hosted. Lots of businesses (maybe the majority) won't want to self-install a piece of software that will generate hundreds, maybe thousands of documents (in addition to the need to manage backups and security). The G Suite alternative needs to follow something like the WordPress model. In other words, businesses can shop around to find a suitable hosting plan for their G Suite alternative needs. Like WordPress, there will be cheap-and-cheerful hosting plans at one end of the scale and at the other end are managed services with SLAs (Service Level Agreements) and premium support. The G Suite alternative will include an API that enables data to be transferred from one hosting provider to another allowing easy data transfer from one hosting provider to another. The "WordPress" model is not a "pure" decentralised model but it's far more practical and more likely to have a chance to succeed.
