Nice pedantry, you're good at purposefully ignoring the forest for the trees.

Industry standard, as in what pretty much everyone uses - you know, a colloquial term, but you knew that and chose to ignore it to get on some high horse.

So you don't get a choice about being incompatible.

I didn't say I liked it, just it is what it is. Let me see you deploy 10,000 laptops/desktops in an enterprise without office, and find out how much that costs you in lost productivity. Or how many things you simply can't do, at all. Like using OneNote, with the server infrastructure for syncing between people with domain level user administration. Nothing, and I mean nothing at all in Linux/OSS world comes anywhere close to the capabilities of ON.

And Excel, again, people have decades of experience and pre-built docs/templates that have little chance of perfectly importing into any other systems.

Similarly, find me a CAD program competitive with Auto desk or Catia that runs on Linux.

Keep on screeching that people should just squander hundreds of man-years of effort to switch, that'll sure convince 'em. People have more important things to do with their time, like the work in front of them.
