Cost of production. You can flow solder over an entire PCB in one go. And
do many PCBs at the same time.
Each crimp would have to be made individually, or with a machine which
did several at once - and it doesn't take imagination to guess what that
would cost.

Also, solder is reliable enough in this context for the design life - say
about 5 years.

FWIW, the harnesses going to those PCBs will invariably have crimped
plugs.

Which are prone to breaking - quite a common problem in boilers
