This has absolutely destroyed Intel's reputation and handed a massive PR win to their competitors (including AMD). Hard to imagine any normal company cutting out their own feet so willingly, this will cost Intel a lot more than it will make them in short term revenue.
They sat on it for over quarter and gave no indication that any sort of trouble was coming up. The CEO even sold stock and made a profit after being made aware of the issue, but before having the issue be announced publicly. I would not classify that as clearly owning up

E3-1280 v5 goes from 32278.00 Apache requests per second to 25399.47 Requests per second. In other words, a Skylake Xeon performs like an Fx Bulldozer after the patch. And Skylake has the PCID instruction too.
Although to be fair, static-file hosting is about as I/O bound as it gets, and these patches affect file I/O the most.
