The examples looked very close to a real device to me. What is the contrast ratio on your device?

The author identified correctly the message colors. "When you send a text to someone, your message floats to the conversation area in a blue or electric green message bubble (depending on whether you’re texting with another iPhone/iPad/Mac user or some other device)."

Many iPhone users make the error you believed the author made. And the criticism would be valid if they never used an iPhone. Please do not use logical fallacies.

Calling the green bubbles not hard to read is your opinion. Opposed by other opinions and Apple's guidelines. Not fact.

The system high contrast mode makes some other apps less accessible. It makes weather icons all white for example.

Your claim about web browsing was false.

The error is in the texts in one of the images. Observing that someone doesn’t appear to be familiar with the thing they’re writing about isn’t a logical fallacy.

They explained correctly. They illustrated correctly. They appeared familiar even if they used the wrong preposition in filler text.

Texts can mean individual messages or conversations. The preposition could have been confusing but not an error.

Saying something many familiar people say does not appear unfamiliar.

It is not necessary to use an iPhone to read users' complaints, read Apple's guidelines, and measure contrast. This is a genetic fallacy.
