It inherits primarily from the idiotic interview loop, and an entire cottage industry which has grown up around it.
I am reminded of this funny Feynman quote (paraphrasing): "The whole purpose of the existence of the Mensa club was to decide who else was eligible to join the club". Now, in all fairness, this is true of all the big tech companies to varying degrees, but boy does Google Cloud in particular take the cake on this one!
Of course, Big Tech does produce very good products, and at scale, but that is being built by about 10% of their engineers. The rest of them work there just to keep the interview loop as exclusive as possible. :-) After all, otherwise, one of them would have actually solved long runningcustomer problems.
Plus the rest of the world is now coming to an agreement that a lot of Big Tech's growth is coming from a lot of unfair advantages - such as massive data collection before it was understood as a bad thing, ability to lobby local politicians at a much bigger scale, ability to influence regulations that hurt them somewhat but entirely kill the competition (GDPR for example), complete lack of accountability for past malpractices (e.g. Facebook's friendly fraud case, for which no one went to jail) because they are now too powerful to actually be sent to jail.
