When Digi-Key started in the 1970's they catered to the small orders, the hobbyists. They had the highest markups and highest level of service.
This made the company, I guess people were willing to pay extra for service (well, along with some surplus cool NS clock modules like MA1010, MA1012 they sold as bait lol).
1-100 lot are stupid expensive now, those markups have increased, and bigger production quantities Purchasing depts are always using other distributors, unless they are forced to use Digi-Key as a source because their prices are silly high. So going after the big fish, selling to manufacturers to hit the bigger volumes- I'm not sure will work because the company was not built on that. Prove it by running your BoM through other distributors and comparing prices.
Whether that reel of parts ends up in communist weapons systems, or a scalper's shelf, or at another competing distributor, or some lowly hobbyist/repair shop, they can't control any of that.
Why are they following some myth of being able to control who their customers are?
