The best way to change the default operator for all of the instances:

kendo.ui.FilterMenu.prototype.options.operators =           
  $.extend(kendo.ui.FilterMenu.prototype.options.operators, {
  string: {
      contains: "Contains",
      startswith: "Starts with",
      eq: "Is equal to",
      neq: "Is not equal to",
      doesnotcontain: "Does not contain",
      endswith: "Ends with"
  }
});

and the complete script:

kendo.ui.FilterMenu.prototype.options.operators =           
  $.extend(kendo.ui.FilterMenu.prototype.options.operators, {

/* FILTER MENU OPERATORS (for each supported data type)

  string: {
      contains: "Contains",
      startswith: "Starts with",

      doesnotcontain: "Does not contain",
      endswith: "Ends with"
  },
  number: {
      eq: "Is equal to",
      neq: "Is not equal to",
      gte: "Is greater than or equal to",
      gt: "Is greater than",
      lte: "Is less than or equal to",
      lt: "Is less than"
  },
  date: {
      eq: "Is equal to",
      neq: "Is not equal to",
      gte: "Is after or equal to",
      gt: "Is after",
      lte: "Is before or equal to",
      lt: "Is before"
  },
  enums: {
      eq: "Is equal to",
      neq: "Is not equal to"
  }
