You are, obviously, free to choose the software you use. What you install on your computer is, again of course, completely up to you.

What I take issue with are people who jump into any discussion of proprietary software and downvote / criticize with "proprietary" being the only point. A fair criticism should take the form "Cons: Not open source", "Pros: ...". But it never does. It's always just "Nobody needs this proprietary crap". That is what I consider actively harmful, because it suppresses options that may actually be useful, if not for you then maybe for other people. If you don't like it, why not just let it be? I don't like JavaScript. I don't go around forums and shout "It's a horrible language!" where ever I see it mentioned.
