> It would still take me just as long to ramp up on the equivalent Oracle offerings
The claim isn't that better names help you ramp up faster. It's that they make it faster to figure out which service you need, or if a service is relevant to you. That said, per the point in my previous post, it's likely that if you can't even clearly describe or name your service, you can't write clear documentation either. I've found that's often the case.

I don't understand what argument you're making. Is it: Since some subset of people will invest time in learning technology even if it's complicated, therefore it doesn't matter if it's too complicated? If so, you'd have to show that the number of people using it wouldn't increase were it simpler, with clearer names, etc.
That seems unlikely. The whole ethos of many successful companies -- Stripe, Mailchimp come to mind -- is to differentiate themselves by simplifying. It matters to the vast majority of users, developers or otherwise.
