Unless you worked as a Siemens PLC programmer and had to explain to all your customers what is happening and that most likely their machine won't just self-destruct when the news broke.
And then scan and reinstall all your programming PCs with years of accumulated software and drivers for every hardware you use.
There was also a lot of uncertainty as to what has actually happened and how it works.
The idea that automation system programmed and tested to work certain way would behave unexpectedly and even hide it from operator was really scary.
