They do suck due to lack of effort or investment. FANG companies have remote dev experiences that are decent - or even great - because they invest obscene amounts into dev tooling.
There physical constraints on the flipside: especially for gigantic codebases or datasets that don't fit on dev laptops or have need lower latencies to other services in the DC.
Added bonus: smaller attack surface area for adversaries who want to gain access to your code.
