Lock Down - price on office 365 something we already paid for and happy with but need latest OS system

What about people in lock down that cant afford upgrade to Office 365 but want to use office 2011 that we have paid good money for. I want my Mac to be update as allot of Apps now will not work on Mojove

This is think is conning us into buying a new program that we have the old version and it works and does everything I need that is fairly basic level. Is Apple and Office in a deal to make more money out of us? And in lock down how disgusting
