You should look at the rest of that site too.
It has freeware and commercial app's
If you add to, modify, or repackage, in any way, someone else's software that is not released under an open source license you are violating EULA's in some form or another.
I don't know what the law is in 'NL' but at least here in the UK you are breaking it.
There are even some scumbags who sell freeware from their own site. Sometimes they change the colour of the GUI.
There is a line that you do not cross, otherwise, where does it stop.
