Don't mean to criticise the open source projects but why hasn't Microsoft done a client that runs on multiple platforms itself, or at least supported for example a Python library? python-onedrive hasn't been touched in a month and since it doesn't support the new REST API, it's crippled for most purposes due to the heavy rate limits on the old API. onedrive-d looks good but it's dependent on GNOME, making it impractical for many use cases, particularly on headless devices like a Raspberry Pi. Microsoft has the power to support this better, why has it chosen not to?
