In addition to the Classic option that is shown only after hitting "Cancel", they also had a secret "Microsoft 365 Basic" option for $20/year. It includes no Office products, but provides 100 GB of OneDrive. Which is all I needed. So Microsoft is getting $20/year from me that they don't deserve.
Why do I pay them even $20/year? It's insurance against the same kind of BS from Google. I back up my Google Drive to OneDrive.
For only 100 GB, that's quite expensive storage. Compare for example Backblaze B2 at $7.20 / year / 100 GB. That is just the storage, so if you do lots of I/O it might increase - but if you aren't using exactly 100 GB and don't do much IO it might also be less than $7.20.
