The reason designers use lorem ipsum is because the text accurately mimics the look and characteristics of latin alphabet languages, without distracting from the design elements.
This makes it perfect for Graphic Designers to use as dummy text in design mockups.
In other words, the beauty of lorem ipsum text is that it has the appearance of English (and other Latin alphabet languages) in print and digital design mockups and yet it doesn't distract the user from the design.
There are a range of alternatives out there (easily found in a google search) but the point is, if you use something that has some meaning, it will be a distraction.
Ultimately it depends on your objective. You might want to augment the design or wireframes by using something that makes sense to the reader. Generally though, at the design stage, you want feedback on the design, not the content. And if you use some other placeholder text that is too distracting, you might end up getting feedback on the text, not the design.
Latin text is a good placeholder because most people don't read or understand latin, and yet it looks more or less similar to English or other latin alphabet languages. It all depends on your objective, and so maybe for a niche audience you would chose to use something appropriate (e.g. if you are building a website for a cheese shop, you could use this cheese lorem ipsum placeholder text: https://www.loremipsumtime.com/cheese-lorem-ipsum/), but if you are designing something more serious, the original lorem ipsum placeholder is probably a safer option.
There are some people who don't like lorem ipsum (usually copywriters as opposed to designers and clients). However, I'd say that it has probably survived as the go to for filler text for over 5 centuries for a reason.
