Your comment was about C# being "the best language in terms of features and improvements", nothing about usage numbers. I agree that C# is far more widely used than Scala, but Scala is being used by significant numbers of developers esp. for Spark. Tiobe is also widely regarded as a pretty poor indicator of language adoption.
