1. Because they confuse Java with the standard hibernate/springboot backends that are used everywhere in the industry. Hibernate/springboot is the reason why there are so many monoliths out there that are almost impossible to refactor.

It's not Javas fault, it's Springs fault.

2. They believe Java is slow, but fail to realize that the JVM has actually one of the most optimized runtimes under the sun and can be fast than (unoptimized) C in many cases.

Long story short: Because they have no clue about Java and follow advice without researching it first.
