Same for it's Java-based cousin, Spring :-)
Say what? That unholy mess of annotations, unusable outside of the Spring "walled garden" where you have to search the internet on how to do the most basic thing (with annotations)? Spring(Boot) is the perfect example --to me-- of a framework that dictates, and does not allow to be get out of your way when all you want is "just libraries".
But I'm inclined to agree on the case of Spring Boot... It's meant to be a "convention over configuration" kind of thing, so I guess by nature it ties you in pretty hard.
