I'm probably reading too much into this, but it feels like this and other corporate announcements are channeling a pretty substantial shift in political-economic mood, theory-space or whatnot. They seem to be justifying themselves in ways that were previously unnecessary.

If Monetarism really is being abandoned, I predict unpredictable changes to economic thinking across the board. It was definitely impactful on the way in. I suppose unicorns zooming past the $trn mark is connected too.

The "cash accumulation" aspect of FAANG economies is (IMO) hard to digest in terms of economic theory. Rather that existing to finance economic activity, these companies make stock markets look like they exist solely for liquidity: cashing out VCs, compensating executives, etc. There is no "I need $1bn to build a new factory or something." There is no equity/debt ratio. Most of the texbook (at least mine, from circa 2003) doesn't apply. Apple/etc have plenty of cash, and don't need capital to expand either way. Economics has surprisingly little (new) to say about why dividends aren't happening, the difference between buybacks & dividends or cash accumulation generally.

I can think ways to "story" cash accumulation. Eg, instead of investors getting dividends and buying Vanguard or Bitcoin, FAANGs might as well just buy the securities on their behalf. This could be an argument, but I haven't heard it made. I'm not advocating it, just eg.

A "hostile" story might be that Apple are hogging all the capital that should be available for Tesla or some other company that actually needs capital.

In any case, I suspect there is more pressure to invest big sums than we know.
