There is no platonic definition for words that make it wrong to use them in a different way.

Dictionaries are descriptive, not prescriptive.

If someone uses a term like "open source" in a way that is clearly different from how you understand the word, that doesn't make them wrong. All it does it highlight a different perspective.

You can attempt to tell them that they are wrong to use the term that way. It's changing the topic and distracts from the point, so if that's your goal, go for it. Most people don't react well to it. You can think that they should be okay with it, but people don't tend to react well to that either.

it's your choice.

I don't think it's wrong. I think it's confusing and creates unnecessary friction. Especially if the term is well-established in the profession or the community.

Does it really? I find I have a pretty common process, where I will hear something and it doesn't make sense to me, and then I pause for a moment to think, and I realize the speaker is using some word or phrase differently than I was expecting. I then understand what was trying to be said and continue the conversation.

This is a daily thing in my experience, often internalized to the point I don't notice until reflecting later. It doesn't feel like friction to me. This is the unavoidable nature of trying to connect with someone using language.
