While it's sad that they are closing, there is a positive take here: there is less need for such a service, because A) there is less variation among processors, so you know pretty much exactly what you are getting and don't need third-party binning to get top performance, and B) Intel has improved their Thermal Interface Material (TIM), so there's no need for delidding. Basically, CPU performance increased and grew more consistent, so you don't need a third-party provider to pick out the good ones for you.
