Fortunately Microsoft Office isn’t fully subscription yet, but with how much they’re pushing Office365 it’s not too surprising that people don’t seem to realize this. You can still buy a permanent license from MS directly (with some digging around to get to the correct page) or from 3rd party websites. Only downside is it locks you into the current version of Office, but for the average user (me) that’s not too much of a big deal - I can’t recall them releasing any major must have features over the past 10 years.
