I'll readily admit that in certain fields (particularly programming, but also programming-adjacent ones) open source software is good enough and arguably better than commercial offerings. In those cases yeah, people are going to maybe have discussions on the merits of using the free software over the commercial closed-source ones. That's how it should be. That's not how it is for a lot of creative fields, though.
I don't think this is really true. When choosing between say, python and Matlab, the price of a license absolutely weighs heavily into the discussion.
