Someone in that org needs to be an adult and say no to pointless rebrands and brain dead consolidation. Literally nobody, even Google, is benefiting from this spastic behavior.
Yep. Making a new thing is how you get promoted. Maintaining or improving an old thing is nearly useless, even at companies with competent managers.
This is the same reason why a lot of companies have awful security practices. From the managers' perspectives, they're burning valuable engineer time on something that doesn't produce any tangible benefits besides reducing the possibility of a lawsuit. And that lawsuit is probably cheaper to just pay up, rather than pay for all that engineer effort.
