Mind your own business!
It's none of your business how I choose to code my own projects.
If we're on the same project together, we can discuss it and decide on a style that works for everyone.
When I contribute to an OpenSource project, I adopt whatever style they have defined.
For my own projects, I have personally opted out of using unnecessary semicolons and brackets unless they improve maintainability or readability. But you don't have to know or care about that.
