Nothing is.
I find explaining a few good computing practices coupled with a tour of the many fine OSS tools available literally for the asking, does real good for anyone willing to invest a bit of their time.
MS Office itself can corrupt its own documents. Ask many of us how we know, right? Now that is more rare than it is for the OSS tools, but it does happen.
You are not wrong. I am not sure what being right actually means in this context too. So yeah. I will just move on.
The most important aspects of all this boil down to people being able to do stuff other people would prefer they not do.
Further, should they be inclined to do said stuff, actually seeing it happen, and or, getting help to make it happen usually solidifies how important "Use Value" really is.
Unlike physical goods, software has the unique property of it increasing in value both as a sum of parts AND as more copies of it are made and used!
Think about that for a moment.
Done?
Great! Fact is that use value dynamic runs counter to our general and natural inclinations. I really enjoy it when people begin to think this way, embrace the tools, understand the culture and share it themselves.
From there, if they can learn to first build and then write software, they will have near fully bootstrapped themselves onto the best open computing and open data have to offer and we all see a fractional value change for the better.
Yeah, probably more of a response than expected. I sure did not start out with all this in mind myself!
It has been a while since I felt the need to express these things in the hope passers-by get something out of it they can use.
