Whenever anybody tries to claim that a non-commercial licenses is open-source, it always gets complaints that it is not open-source. This particular word hasn’t been watered down by misuse like so many others.
There is no commonly-accepted definition of open-source that allows commercial restrictions. You do not get to make up your own meaning for words that differs from how other people use it. Open-source does not have commercial restrictions by definition.
Looking up open-source in the dictionary does include definitions that would allow for commercial restrictions, depending on how you define "free" (a matter that is most certainly up for debate).
The term "open-source" exists for the purposes of a particular movement. If you are "for" the misuse and abuse of the term, you not only aren't part of that movement, but you are ignorant about it and fail to understand it— which means you frankly have no place speaking about the meanings of its terminology.
This kind of thing is how people try to shift the Overton window. No.
