If they didn’t properly redirect their previous /blog/ pages to the subdomain, then organic traffic would have definitely dropped.
Unless the company is an enterprise, it’s usually best to keep the blog as a subfolder as opposed to a subdomain. I read some study a year or so ago where they compared subfolders to subdomains, and essentially the difference between the two were not statistically significant enough to say one way or another.
There are a lot of variables that go into page performance. Usually, these issues come down to content. Individuals and companies often times overestimate the quality of their content. Without looking at any direct data, it’s hard to give any sort of definitive answer to this question.
