I'm not letting the developers entirely off the hook. At many companies, they are decision makers too, and partially share the blame with their product leadership and other decision makers.
Unpopular Opinion, but if you have absolutely zero say in the content of what you're developing, and just take orders from JIRA, you shouldn't call yourself an engineer. You should also keep your eyes open for a better job.
Agreed. Plus, if you can get an entire team to tell the PM “this is fucking stupid, we aren’t doing it,” what are they gonna do - axe an entire team? I doubt it. Maybe at big companies, but small ones? Nah.
