The point, which seems pretty clear to me, is that if you are going to dramatically disrupt the lives of 7000 people while reporting profits in the tens of billions of dollars, 19% higher than the previous year[0], you are cruelly exploiting the pain of others in pursuit of needless profit. If you then show up late to meetings and make jokes about it before jetting off to an extended vacation most of us will never have the wealth to experience, you further reveal that you have no regard for what you've done to the 7000 people whose careers you've sacrificed to juice your quarterly bonus.
This is more than "perhaps inconsiderate," it is pointlessly cruel, a mark of someone completely out of touch with his current and former employees, an indicator of someone who puts profit above literally everything else, which is not okay.
The point is that not only is the timing woefully insensitive, but the duration, locale, and purported reason ("digital detox") serve to painfully highlight the inequality between the CEO and the people he just made unemployed.
I don't know the specific demographics of the 7k that were laid off from Salesforce, but the chances are fairly good that some portion of those will end up homeless or near to it due to the loss of income before they can land another job. Those chances are highest for those who are already in the worst shape (particularly those with chronic illnesses or some form of disability).
But the CEO is "mourning" these people so hard that he has to go on a (guesstimating) five-figure vacation to the tropics...?
the timing of the vacation is perhaps inconsiderate, but not sure what points we are making here
