This is true. You can get "industrial" versions of these cards that are intended to be used as BOM items for products. This means you get a stable supply and they won't change the part number out from under you (which happens even with reputable suppliers when you buy as a consumer). When they're about to EOL the part, you get a heads-up multiple months in advance and a "last time buy" opportunity. In my experience, these aren't "better" performance-wise. You just "know" what you're getting, have an opportunity to qualify it, and you won't get surprise changes. Of course, the price is jacked up as a result. Generally speaking, it's usually better to make the customer responsible for the SD card if you have to use one at all.
