People often say this and it makes me wonder how old they are. Do they not know how business works? Thousands of people get fired every day and the threshold isn’t “harming someone”. More often than not, it’s just “providing an unsatisfactory performance”.
Now people may differ on how unsatisfactory Didio & co. have been but stakeholders (which is what readers are. After all: no readers; no comics) who think they’re driving the company into the ground are well within their rights to call for their replacement.
