I feel like a portion of it is the way that many/most companies have been captured by their finance departments. Everything is accounting. The CFO in many organisations has become the most powerful exec, and many CEOs seem to come up through the CFO role.
Outside of places like Meta, who are printing money at a ridiculous rate, finance acts as a break on any long-term or big bets. There can be no risk taking.
I feel like this is one of Google's problems now. Once upon a time they were willing to take big swings with their piles of cash, now it's all about revenue maximisation at the low level. I forget which change it was, but they started charging for something, or limiting quotas on something, and the email contained the phrase "in line with industry norms", and I just thought that was very tellings. Back in the early 2000s Google was constantly defying and upturning "industry norms", now they are just like everyone else, squeezing every last drop from the smallest stones. Getting rid of the previously grandfathered in free Google Workspaces was a good example. I find it hard to imagine that the cost of those even registers in their accounts compared with everything else.
