What usage does 有 have in ~的有 (e.g. 偏向于data reseacher的有) In the following sentence over 知乎:

从我的观察来看，不同企业对于data scientist这个title的定义其实是有分歧的，偏向于data reseacher的有，多见于大型IT企业，百度大脑的data scientist们多属于这一类型，他们搞的是比较前沿的深度学习，平常会读大量paper可能自己也会发；偏向于data creative的有，各种企业都会储备，会ETL，懂模型、懂行业，会展示沟通，比较能够创造直接的价值。偏向于data developer的也有但是很少，他们不懂模型，只要给他们算法公式，他们就能用编程语言帮你实现，实现算法是重要的技能，但是这种不懂模型不懂行业的，现在大多企业都不太会给这样的人data scientist的title了。

关于偏向于data researcher (or suffix &quot;的话&quot; here?)，
关于data developer，虽然他们比减少，

However, grammatically how does 有 work here? I just check out the Chinese grammar wiki but didn't find any relevant pages.
I am a native speaker and consider myself a "data" person.

From my perspective, he didn't end the sentence properly and his array of sentences could be changed a bit like below so it's easier to understand.
