Tuples should not be described as immutable

[jedr]

Tuples are actually mutable.

As detailed here: https://docs.microsoft.com/en-us/dotnet/articles/csharp/tuples

All the ValueTuple types are mutable structs. Each member field is a public field. That makes them very lightweight. However, that means tuples should not be used where immutability is important.
