Early on, chip manufacturers and software publishers rushed to release mitigation code, some of which had significant unintended consequences, including multiple system reboots and dramatic application slowdown. Since those early days after the vulns were disclosed, the response has become more measured. But many customers are still wary of any response — especially since many of the updates are either mandatory within an operating system's update stream or baked into new releases of hardware and software.
