As a former blue apron customer I don't think it was ridiculous. I churned when my wife was out of the country. There are still recipes that they sent that I still cook. Now as a business I don't think they will be able to compete with a hybrid solution that amazon/Whole Foods will be able to devise. But I see Juicero as completely different.
Juicero was too visible in high-standard markets and thus became an easy target. Whereas Blue Apron flew under the critic radar (mostly in Facebook mom feeds) before gaining enough market share for consumers to shrug off ridicule
