It's funny that a lot of this is people with bullshit jobs trying to justify their existence. A company this big gets bloated internally with staff - especially middle management - that will manipulate information to prevent themselves from becoming redundant, so they will insist that their specific project is super important and they absolutely need every engineer working for them, because their prestige and pay are connected to how many people they manage. So then your software fills up with useless junk until the problem gets so bad it can't be ignored. There's a big internal shake-up and products get rebranded but most of the organisational bloat remains, so the cycle starts again.
