Like a privacy based fully open source browser. Wouldnt it be more hackable because every one know the script and is a glopal privacy based gpay alternative possible ? What about targeted hacking is someone using closed source application more better off than someone with ooen source ?
Code security is directly proportional to the amount of resources devoted to finding and fixing bugs regardless of open or closed. If nobody is maintaining the code, it doesn’t matter.
One advantage with open you is that you can look at the version control to see how active the code is being maintained.
