Really? I quite like them. I did get used to them in C# first, though. What would you have preferred?

From a language design perspective, fat arrows make parsing unnecessarily complicated because you cannot distinguish "(a, b, c)" from "(a, b, c) => ..." without looking ahead or backtracking. Certainly not difficult to solve, but this choice makes extending arrow syntax more difficult and the fact that a production called `CoverParenthesizedExpressionAndArrowParameterList` exists in the language grammar is a pretty ugly IMO
I would have preferred a word.

const my_arrow_function = arrow_function(){}

arrow_function my_arrow_function(){}

arrow_function(){}

In older C#, that would be delegate:

    delegate(int x){ return 10; }
(But yeah, nowadays that would be:)

    (int x) => 10
