It's morally wrong to promote bad things, and morally good to promote good things.
Just because I admire the theories Isaac Newton came up with and I encourage others to learn about them does not mean I support everything Isaac Newton did, said or thought.
All of our society is built on the shoulders of giants who did a lot of "good" despite being, in most cases, "bad people".
The more people learn to drive, the bigger the chance they'll get a private car, the more accidents, the more people will die. Thus: let's recommend everyone to not learn to drive.
I feel this path is sort of a baby-sitting approach to recommendations. Not only do I have to know if the software if good before recommending it, I also have to research if there's a chance that whoever I'm recommending it to might find a community somewhere for which they might lack enough critical thinking to judge on by themselves?
How about we recommend good software when it's good while at the same time recommending good ideals / good thoughts when they are good?
