But I would also say that the companies using query syntax are also vastly underrepresented on GitHub public repositories.

I think beyond that, it's probably more common with developers that came from doing SQL queries but "needed" type safety.
I've worked with developers that didn't even know the extension methods existed. They went from SqlCommand to LINQ to EF or LINQ to SQL.
The only time I think query syntax is better than the extension methods is when dealing with table joins.
