MS Office is around 150 USD per year (on Premium Plan, and it comes with 1TB/user of OneDrive: good luck beating that package), I would imagine it would be less for large corporations. This is really not much for a software platform that any white collar employee knows how to use at least at its basic level. Excel and Powerpoint are critical software for most large companies. Budgets, financial analyses, forecasts, quick calcs, presentations on factory shop floors and in board suites rely on them. I am a management consultant so I see a wide range of corporate tools: I have seen large companies use Google as their cloud, email and calendar platforms, dropbox for their shared drives, PowerBI or Tableau, SAP or Oracle or Salesforce for ERP, but not even once I saw a company not relying on Excel and Powerpoint for much of the daily activities. They wouldn't risk getting away from PPT and Excel (and, to a lesser extent, MS Word). The certainty that somebody in another country or organisation will open the file and it will appear as intended is essential to large (and small) companies. Plus there is almost no training needed for new hires, as both student and expert hires will have experience with it. Today MS Office for MacOS is quite good: some functionalities are missing, I think, but what is there is 100% compatible with Win platform - I wouldn't bet on this to be true for LibreOffice. If a company wants to save money on licenses it might be netter off reviewing how often certain software packages are utilised and prune based on this, rather than blanket-switching an almost universal software, used daily and that is not even that expensive.
