Is it though? I see whole corporations running in office. Most communication goes through outlook and PowerPoint. I’ve seen people building intricate and bespoke interfaces in Access with only later the data storage layer removed from access internal to ms sql; whole graphs and pivot tables created from many data sources in excel, and even finite state machine simulators integrating real time Prometheus dashboards. Somehow the office suite is extremely powerful and it works and integrates with many things. It may not be pretty but I’ve seen many non(CS)-programmer deliver quite some business value with it.

Not really. And everybody knows Microsoft anyway.
