Playing with NextCloud
Google, Apple and Microsoft have cloud storage solutions. So does Evernote, Kdrive and other products. The issue with all of these solutions is that they are owned by corporations. They are simple and convenient to use but at the cost of being locked in to an OS in some cases, and to corporate interests.
NextCloud is an open source alternative with hosting solutions that offer people with the choice of choosing between hosting solutions that are as local, or as remote as they want.
