The landscape has been changing rapidly since .Net Core (now just .Net) matured 3-4 years ago. As you say there are a LOT of big enterprise shops out there using .Net, but more and it's catching the attention of small companies and startups. I work at a small-ish (~300 employees) B2B SaaS that has a wide variety of legacy code bases: .Net Framework, Node, Ruby, Php, and a few others. We made the decision last year to make .Net our default choice for new projects.
