This is clearly a case of someone not knowing the limits of a technology / how to select or use a technology. Yes, more modern versions of Excel support many more rows than 65k. As a "power" excel user in the early 2000s, it's tiring to see this same mistake made. And I might have blamed MSFT in 2008. But the "modern" world has taken an absurdly boorish response to this virus. This unfortunately looks like another example.

Forgot to mention: there's nothing inherently wrong with storing data in CSV files. One does have to think about consumption and processing. A Postgres database seems pretty reasonable to track information like this, but I wouldn't blame a CSV format for shortsightedness. We're not talking about actual big data here...
