The article title is bad, and should feel bad.

I just read the article. I must have missed the part where representatives of the supermarkets gave their support.

Edit: They based it on hearsay

The developer of a grocery price comparison app says supermarkets have responded positively to the online tool.

At the end of the article it was revealed that supermarkets are not good at helping developers of apps. So they undermine the premise of the title.

Wong said he would like to see supermarket vendors help app developers.

"I hope the vendors can provide a public interface for developers like me to build these kinds of third party apps to facilitate price comparisons and all other kinds of grocery activities there."

Also the following hypothetical doesn't make sense to me:

"They could have a consumer facing app where you can go and put your grocery list in. Then with AI and algorithms they can work out your best price and say we are placing the orders with these supermarkets.

"So you can get three deliveries from three different supermarkets with the best price. I believe that is something that will force all supermarkets to bring prices down."

Wouldn't three deliveries mean paying three shipping fees? Wouldn't those shipping fees eat up the possible savings?
