Look at any FAANG/MAANA and ask the same question.

If I had to guess, most of them have so much cashflow that mid and senior level managers are able to do engage in organizational silo-ing by hiring a large amount of expensive engineering talent without much pushback.

If this is the case, there's likely a large pool of talented and highly compensated employees doing work that doesn't touch on either a profit center or high-impact research & development. And what work is being done is likely influenced by Parkinson's Law.
