Why has Desktop Launcher blocked running scripts?

Today morning, I tried to write a desktop entry file to execute my small and cute bash script for my beautiful IDE ‘NetBeans’. There was no problem until I did double click on the iconised desktop entry file. After the click, I got an unexpected error(?) message that ‘Untrusted Application Launcher’. I respond “Oh my days!” .

I searched for some information on the net. But, there was no article to clarify what it is..

After that, I opened some of default desktop entry file come along with Linux Distribution. I found that there is no desktop entry files which are running scripts. That means “Don’t try to run any types of script, It’s blocked”

I couldn’t understand fully at first because of my impatience. But, I realise that it could be a security vulnerability. Try to remember that we’ve got lots of macro viruses when we’re using spreadsheet app. What if the launcher let run script directly like spreadsheet macros? Never ask for it!
