Thanks fro reminding me of Shred, though I'm not sure whether it does the job it is supposed to on SSDs.

Normally you don't blindly install software. The internet allows you to check if there is a living community around it, if it's supported, if other people use it to their satisfaction etc. In the open-source world, "garbageware" will soon be isolated and disappear from people's radar.

Or do you have an example for garbageware?

FreetuxTV, xSane, PySol card games.

I haven't used xSane but the other two seem to work well, what is your issue with them?

xSane just doesn't work. I use Simple Scan which is great. FreetuxTV doesn't work. You click on it to open and the searching for channel box opens and closes one minute later because it crashed. There is no support from FreetuxTV but the Ubuntu forum figured out the problem. You need to use the outdated older version of VLC player. PySol card games everything is so tiny that you need a magnifying glass to see anything to use it and there is no way to resize it. The good thing about Linux is, if it doesn't work. Un-install it. It didn't cost you anything other than wasted time.

Then your problem is with Ubuntu's packaging of freetuxtv or, even, issues with the encoding the people producing the feeds are using -- the freetuxtv coders have no influence over any of that.
PySol looks fine to me but, perhaps, it relies upon some config files?
So, we have xsane which, perhaps, is "garbage"?

So let's have a look at FreetuxTV. I didn't find a web site. I did find a Linux MINT community page with tons of dismal reviews. It does seem to be garbage, but I don't need to be warned about it. I find the warnings myself.

PySol does have a web site, and it says "As of 2004 any work on PySol has stopped, and PySol is officially discontinued.". Do you need a warning on top of that?

Similarly xsane.org:
Again: I install open-source software if I see that there is an active development and user community around it, if I see other people like it, etc. I don't need anybody warning me about the three examples you chose; it's obvious that I should be careful if I really need to install them.
