I suppose that depends on your relationship with your employer. If your goals are highly aligned (e.g. lots of equity based compensation, some degree of stability and security, interest in your role, healthy management practices that value their workforce, etc.) then I agree, it’s in your own self interest to push back because it can effect you directly.
Meanwhile a lot of folks have very unhealthy to non-existent relationships with their employers. There may be some mixture where they may be temporary hired/viewed as highly disposable or transient in nature having very little to gain from the success of the business, they may be compensated regardless of success/failure, they may have toxic management who treat them terribly (condescendingly, constantly critical, rarely positive, etc.). Bad and non-existent relationships lead to this sort of behavior. In general we’re moving towards “non-existent” relationships with employers broadly speaking for the labor force.
The counter argument is often floated here “well why work there” and the fact is money is necessary to survive, the number of positions available hiring at any given point is finite, and many almost by definition won’t ever be the top performers in their field to the point they truly choose their employers and career paths with full autonomy. So lots of people end up in lots of places that are toxic or highly misaligned with their interests as a survival mechanism. As such, watching the toxic places shoot themselves in the foot can be some level of justice people find where generally unpleasant people finally get to see consequences of their actions and take some responsibility.
People will prop others up from their own consequences so long as there’s something in it for them. As you peel that away, at some point there’s a level of poetic justice to watch the situation burn. This is why I’m not convinced having completely transactional relationships with employers is a good thing. Even having self interest and stability in mind, certain levels of toxicity in business management can fester. At some point no amount of money is worth dealing with that and some form of correction is needed there. The only mechanism is to typically assure poor decision making and action is actually held accountable.
