No argument that there is a lot of bad software.
I am not as much on the bandwagon for “there is no lack of supply for software”.
I think more software is good and the more software there is, the more good software there will be. At least, big picture.
I am ok with there being a lot of bad software I do not use just like I am ok with companies building products with Open Source. I just want more software I can use. And, if I create Open Source myself, I just want it to get used.
