In my experience, Raspberry Pi DIYers are more than happy to talk about their experiences, but they've only got small sample sizes, they're buying things at retail, some will be relatively price-insensitive, and people who have problems might be particularly eager to complain. These people hate SD cards with a passion. The kind of people who are in a position to report on failure rates across a fleet of hundreds of SD cards (a) don't always have their employer's permission to talk about it, (b) don't want to publicly bitch about vendors they want to maintain a good relationship with, (c) can be very price sensitive depending on the product and (d) are often buying through special channels where vendors will do things like guarantee a specific controller firmware version. These people keep on releasing products that use SD cards.
