I agree. The whole idea of the sample policy is for companies to be able to get parts easily and quickly without having to buy them. This makes it easier to develop products that use those parts, which makes the component companies happy.
These suppliers expect this sort of flow:
Samples -> Prototype -> Qty Purchase
The "abusers" do this:
Samples -> Prototype -> No Purchase (or more samples!)
Abusing the sample policy just makes it harder to get parts for those of us who might actually be purchasing them. Maxim has a bad rep for long lead times anyway!
