when I am supposed to fix tech debt? if every week there is another functionality going out that needs to be done yesterday? Do you think that I have to do it in my free time? Why should I even bother existing
You are blaming the system S. However we have counter-examples where the problem P occurs outside of the system. If P occurs without S then possibly S is not the cause. Admittedly untangling causation, sufficient and necessary is difficult.
The article itself appears to be a counter-example that is non-commercial: where problem P occurs without system S.
I think it is worthwhile investing time to work out for yourself when to honestly blame commercial constraints, and when to recognise other root causes. Blaming the system by default is unhealthy IMHO.
