Making Windows open source has been brought up before, and I’m just quoting what has been said and it could be wrong, but lots of people made the claim that Windows is such an old codebase with 25+ years of different people (and, sometimes, companies) involved that it’s a huge legal task to be able to open source it. So even if it was in the interest of Microsoft they’d have to remove a lot of legacy code or track down individual contractors and get permission to do so (not to mention hardware support that may have been given to them under a proprietary license.) Again this could be bs, I’m not sure, but it makes sense if this is the case.
