Your random SaaS company is often a big shitshow. I've had more than one vendor Sales Engineer show me live customer data in response to performance or other questions. Startups and smaller SaaS companies in particular often demonstrate amazing levels of cluelessness.
We had an e-com SaaS company give us "sample product data" to help one our customers who was onboarding to their platform and was trying to figure out how to set up their product records and taxonomies, and the data turned out to be poorly anonymized real production data from one of our client's competitors who was also on the same SaaS platform.
