LibreOffice is an open source project and has always been free to download, even for commercial use, but the app in the Microsoft Store carries a price tag of $2.99/£2.49. > The app description suggests this is just a way for the software's creators to solicit donations, and selecting 'Free trial' rather than 'Buy' will download the full suite with no strings attached.
