Jason Snell (I believe) mentioned that while he doesn't understand why Apple still offers it, he thinks it might be because it is the laptop of choice for business/enterprise/institutional purchasers and they buy millions of them every year so Apple keeps offering it.
And I think this makes sense. The 4-port 13" Intel model was very popular with software developers at a former company I worked for and we bought thousands of them every year. These folks needed sustained CPU performance (which the fan could help with) and they used the TouchBar in their daily workloads. And considering it is still far cheaper than the 14" MacBook Pro, I could see this being a very popular model with corporate IT departments.
So yes, this is a very poor choice for consumers, prosumers and many professionals, who are better served with an Air or the 14"/16" MacBook Pro.
But it seems to be a very smart choice for certain classes of professionals that are large enough to keep the model relevant in Apple's product line.
