This is so spot on!
This isn't exclusive to supermarkets but many other industries and the problem is always the same. Someone looks at the bottom line and realizes that hey 50%, 60%, 80%, of revenue comes from product A, and B through F are just producing 10%, so why not get rid of them, or call them a failure. But what they are missing is the bigger picture because the user experience that drives to go with Product A needs the other products.
It's really interesting that such simple concepts are missed by most people in management roles, and even though here you have a brilliant and simple explanation, most people don't get it.
This is a bit off-topic in a sense, but this one comment just really hit on something for me that I've been dealing with for two years and I'm going to be sharing this explanation with other people because it really captures this specific problem is so perfectly.
Thank you!
On the subject of Youtube, this is a pretty massive change, it is definitely not a benefit to a lot of creators, but as others have said, Youtube is really the only game in town. Vimeo basically disappeared into a premium offering, so they are acting a bit more monopolistically.
The funny thing is if they never really had low standards to share monetization, I don't think that would have affected the way creators create and upload content, but now that they gave it to them, and are taking it away, it's going to cause a backlash for sure. Unfortunately, there's no clear #2 for those creators to goto.
