I don't buy that. I actually see Angular being USED in big corporate environments. I hear from friends about how their team is USING it.

I hear people TALK a lot about Vue. Nothing against it, I enjoyed my little hobby project in it. But way more people talk about using Vue than actually using it. In no way is it "eating Angular's lunch". This is coming from someone quite critical of Angular.

Vue is great, I love it for my personal projects and it's also fairly common in PHP world but that's it. Angular is very popular in Java world and it works really great if you need a lot of forms. These people usually don't have time talking about it. React is popular everywhere else, especially among bloggers who usually fail to explain why exactly is React better choice.
