While I am happy that Microsoft have softened their stance on open source, as at one point they were firing off sue balls in all directions for anything that might have breached a Windows patent. But their new approach isn't about them necessarily seeing open source as the future for MS, (as I would be very surprised if the ever open sourced Windows, office etc. even out of support editions or started to contribute towards Libreoffice, ReactOS). But its about how they have realised they can make money from open source, use it to their advantage, such as the recent switch of Edge to Chromium engine, and having competition reduces the risk of anti monopoly legislation causing them to get broken up, fines etc.
