Say your app takes 5 minutes to load the first page and 1 minute to switch between pages after that. Instead of blaming the developers, blame the users for expecting too much of the app. Personal responsibility and all that.
It's the users fault they are using the app during peak times. If they really needed access to X part of the app they should have done it before it got busy.
If you're morbidly obese, it is because you chose to eat too much and you chose to exercise too little.
It was your choice to stuff all that food in your face, no-one else's. You did it.
People are hungry across the world because there is a lack of food. They cannot just decide to feed themselves food that does not exist.
Terminally online cryptobros who get triggered by comments like "It was your choice to stuff all that food in your face, no-one else's" are not suffering from a lack of food, they are suffering from an excess of sugary poor-quality food. You decided to stuff that fourth twinkie in your face hole, you fat fuck. You can also decide to *stop* stuffing them in there.
Not you *you* obviously, the rhetorical you.
Since we're in a technology forum. Let's say you're a product owner and your app is suffering from severe performance issues. Would a "solution" of telling the developers of the app "just write code more efficiently! Use Google if you have to!" be acceptable to you? Do you think it would produce the results you want?
