Hypothesis 2: this is why you have a lot of anti-capitalistic talk among tech folk.
The whole concept of "anyone can replicate my product, but I got here first, so i have to use lock-ins and other ethically questionable things if I want to keep my spot" is antithetical to the goals of capitalism i.e companies out-competing each other constantly, leading to better and better products.
The equilibrium with monopolies that is possible under capitalism is reached really, really easily in tech. Because being a monopoly/locking-in, not open sourcing, etc, is the only way you can be a big tech company.
In my opinion, industries with low barriers of entry are fundamentally incompatible with - atleast the current flavor of - capitalism, if you use user harm as the metric.
