Hi Robert, thank you for this valuable comment!
I also work for one of the biggest company on the market and since few years I see their improvement in allowing people to work remotely - but mostly as a temporary thing, not permanent. My team is kind of experimental one I guess and I am actually preparing to present how my team is going remotely to wider audience, so it may convince other departments to allow the same.
For the licensing this is indeed an issue, but if you get company laptop and use VPN, at least in our set of software, there are no limitations. My main toolset is O365 (Skype, Exchange, Teams, SharePoint, Yammer) but that's true that some job still needs to be done onsite - but I am strong believer this will change in near future as well.
