No you are absolutely wrong. Laziness is not a factor.
Have you ever had to develop and release an application across 5 operating systems all with different UI APIs while also offering a web based UI too? Perhaps it actually makes a lot of sense to consolidate your code base so you can focus on feature development instead of OS compatibility issues and managing many versions of your software across os targets? This is why electron is appealing. In my experience most people who dislike electron apps are speaking from ignorance. They usually have some sort of irrational prejudice against web technologies.
