#155597 - ... or stupid Erik, maybe?

The boss probably got a good deal on those shift registers, and has a barrel-full in the stock room

If you base new designs on what you get "a good deal" on or what you have in the stockroom, you will invariably be screwed some day.
"a good deal" could mean counterfeit.
"have in the stockroom" could mean discontinued while you still produce the thingy.

Well if you've presented the better option and the boss still wants to use the stuff in the back room, it's his choice. You've done your job once the option is presented. After that, it's a business decision.

I can see the above (deal/stock) possibly being meaningful for parts that actually cost money, but to be this stupid to save $0.11 takes the cake.

Yes, in this case, it's hard to understand why one would choose the 4000-series over the 74HC series. However, the decision is not always up to the design engineer. If it were always up to me, for example, I'd never, Never, NEVER use an MCU with positive-going reset, or, for that matter, with positive-going interrupts. Sometimes we have to do what we're paid for, however.

It could just mean that you get fired if you don't do what the boss wants. After all, he's the one who pays for all this. You don't know what his reasons are, nor is he obliged to tell you.

If you don't like the way he runs his business, you should work for someone else.
