I’m honestly not even sure what the author’s point is since IIS isn’t exactly popular, or even any sort of default these days.

I build using Microsoft technologies, and haven’t touched IIs for more than 8 years. I almost entirely use OSS projects, on linux.

From writing, to testing, to IaC, to the runtime, the server OS, the webserver, the proxy…etc is all FOSS projects these days.

The only proprietary things I used is the hosting provider itself and their services, and my IDE.

All that said I want to see Microsoft to succeed simply to spite AWS. We have to have competition, and for the love of god I do not need AWS taking over more of the ecosystem. More competitors more better.
