Except, how do you convince all the other engineers the tech stack is both shitty and that switching off is worth the switching costs? That your data is empirical and also not the "lies, damned lies and statistics" thing where you cherry pick data in your favor so you can look empirical when you are actually just going off your own vibes and ego? Even if your intentions are pure, others might not think so (whether because they have ulterior motives of their own or not).

Unfortunately, that is politics.
