content: If you seriously think that Open Source software is amateur or offer weak protection, I throw for you a trivial challenge:    LibreOffice is pretty much the mainstream Office program in the open source world. Its spreadsheet software (Calc) provides an encryption mechanism through its save with password feature. If you can find out how to bypass that protection, you'd convince a lot many people supporting your view. Interested?    Bear in mind that the mainstream non-open source spreadsheet program (MS-Excel), also offers the same encryption feature - but that security can be bypassed by using Google-able instructions for most, if not all versions. If open source programs are indeed weak and amateur, it would be easier to break their security.
