My usage of the word tech is with regards to systems in place that support business processes, so that includes the Excel Spreadsheet all the way up to the ERP system. I'm sorry, it's hard to go to a company that has already invested in the Microsoft stack, have developers that work in that stack, have many internal and third party applications, have SharePoint all over the place, that run on ASP.NET (and hence IIS), already have sunk costs with SQL Server and Windows servers and make a strong case for changing over. The case might be easy for SQL Server (use PostgresSQL instead) but generally its a no go. I know you used this as an example, but like I said, a lot of it depends on the company. Anyway, interesting discussion for sure.
