No, they're right: your understanding of each other diverges when you write "it's not because of any technical difficulty" --- correct, we all agree there. However, it is still difficult.
Big companies have big processes and that, at least at Google, would have prevented this from happening for at least 12-18 months. Then those things aren't pursued because of A) the literal cost of getting that arranged over 18 months B) the individual's decision not to invest in beating their head against a wall for 18 months for something that'd be done in a week if leadership cared. Leadership does not care, so QED, it will not be a positive for your career.
Things either get done because A) leadership cares and has skin in the game and everyone is afraid of getting in the way of whoever delivers B) leadership cares and will keep asking about it over and over again for a year or two or C) no one cares so no one will get in your way.
That's also the crux of why things at Google go sideways. A) is only true over a year long cycle (I.e. you need to get to launch) B) people are afraid to do because it's hectoring and C) if no one cares its probably not much of a game changer anyway, there's no incentive to do it, and especially in FAANG's Efficiency/Focus(tm) era[^1^], you can actually get pretty easily brow-beaten for it by middle management. Then what are you going to do? Appeal to a VP that your manager and managers manager are big ol meanies?
