The fact that you are arguing against this might be why you are getting downvoted. The original comment was saying “if you are in a small org you probably haven’t worked with SAP”, which is not the same thing.

Edit for further clarification: I can see how it might look like they were arguing what you stated, but it was more of a Bayesian inference. Many HN readers are at a small company, therefore a plausible reason that an arbitrary HN reader might not have heard of SAP would be that they are in the large pool of HN readers that are {in small companies and, therefore, do not work with SAP}
