Occam's razor also needs to be applied. If the explanation involving malice is the simpler option that makes fewer assumptions, then it is more likely.

I bet this has been discussed internally, but nobody cares because they don’t care about UX enough. They don’t understand the impact. The internal organization is fractured into fiefdoms defending internal services (e.g. deployment, AMP) and defending layers (e.g. SRE department), with nobody left responsible for the complete, vertically integrated user experience.

To me, this is a simpler explanation than malice.
