For those unaware - he is talking about 20+ years old events & tech which is long gone. Oscillators and crystals are way different today.
The only thing which might have improved is the awareness of the IC designers and I am dubious about that when it involves analog circuits. Crystals are the same but with a smaller selection and CMOS oscillators on lower voltage processes are worse.
It still happens that designers report with crystal oscillator problems on new microcontrollers. Some have even done so on EEVBlog.
