How do you know production cost is the reason for not using antiskate, and not a different reason like a better design?
Because there are skating forces which affect all pivoted arms and omitting antiskate altogether is not good design. Likewise using a method like arbitrarily twisting wires when there are better ways to implement it, is not good design.
A cheaper product can, of course, be a good design. It depends on the design criteria, if one of those criteria is lower cost.
And as far as costs go, of course it is cheaper to omit antiskate. How much is saved depends on the nature of the device omitted.
Whether that saving is passed on to the customer is another matter.
And whether or not antiskate is used at all is another matter again, and to do with personal reference and nothing to do with good design.
