What I mean by that is something without network effects. If your company uses Google Docs, you don't have much choice because that's where everything is (modulo apps that can sync to it so you can use a different editor).
For something like VSCode, at the end of the day it's still just a text editor. My use of VSCode doesn't stop my teammate from using vim.
For something like that, do you know how much of a pain in the ass it is at most companies to get them to buy something? The issue isn't even if it's $5 or $500. It's just going through the process of figuring out how to buy something, getting approvals, figuring out how to deal with the invoice, etc. Unless I'm already super committed to it, there's no chance when I can simply download any number of free options out there.
