Moments ago, while trying to find the answer to my above question, I read
this:
https://sourceforge.net/p/smplayer/bugs/695/
> "smtube has essentially become a web browser that relies heavily upon
Tonvid.com for its functionality. The problem is that it appears according to
the terms of use found at Tonvid.com that it is not released under a free
license making smtube heavily dependent upon non-free software which
undermines those that wish to use it because it is free software."
So doesn't this mean it is not "free" and I should remove it?
