You're not wrong, but office users should be locked to a browser in 2022 anyway. What do they need Windows for? They can all use a web browser. Microsoft has done an amazing job convincing the office world they need Windows, when they don't need a single feature that it provides in 99% of cases.
As an officer worker, there are many many things I do that cannot be done in a web browser. File comparison tools, macros and complex excel queries, hard applications for both new and legacy critical programs... Can this be done on Linux? Frequently. Can it be done in a web browser? Rarely effectively and often not at all.
File comparison, hard applications, legacy code, can be compiled to WASM and run quite well in the browser. The pieces are in place to do it, they just need polishing and tuning to make it ubiquitous. Even Excel could be compiled like this but again MS wants to own you and pin you over a barrel while extracting everything they can from you, so Excel won't be available. But many/most Spreadsheets can be done in Libreoffice, or code or no/low code alternatives.
