Is the market really free enough for WFH vs RTO to be visible?
The only way dominance can be sustained is by using the government to throttle the competition.
For instance, IBM is a recognized mainframe monopoly. They are not valuable today not because they lost the mainframe dominance, but because mainframes are obsolete (or almost).

Markets are always changing. Large companies tend to optimize for a particular market, and when it inevitably changes, they cannot adapt and get left behind. Often its their competitors that change the market.
See the classic book "The Innovators' Dilemma".
