Are all Google Chrome extensions open source by default?

Question

I want to know if i write a Google Chrome extension, will anyone be able to use my code?

Answer 1

Even though Chrome extensions' source code are accessible by the public, it doesn't mean all Chrome extensions are open source. Actually, you don't have the right to copy/reuse/modify their source code either partially or completely, without their authors' permission, except when he/she has announced that it's open source.
