Why do Intel change socket type?

I can't get my head round when Intel changes socket type so often? Do they have to? I could understand why they might do it if they were the motherboard manufacturer also (to sell. More motherboards). But they aren't. Surely this hurts their CPU sales changing socket type? I mean, if it were the same socket. I would. Probably have bought a 6700k by now. But as I need a new mobo and ram also. I'm leaving it a couple generations.

Maybe they are forced to? But I would have thought it would be in their best interest to keep the same socket going as long as possible.

Motherboards are cheap as chips, so this is an non issue IMO. DDR4 is also cheap as hell.

I guess that all depends on your definition of "cheap as hell"...
