On the other hand,

Some folks appreciate it when someone takes the effort to kit-up
or make a commercial product out of a common design and makes it
available to others who may not have the time to do their own...
Nothing wrong with that.

As  you said, it was off list. And it sounds like he thought the
person was intested in a Helix antenna.  He has them.  SO
nothing wrong with that.  In fact, that is a better approach
than a message to ALL...

Leave me out of your 99%.  I appreciate when any ham takes the
effort to commercialize something for the benefit of others.  If
you don't want to buy it, that's your choice.  But do not condem
the person for trying to help out others.  It takes a lot of
effort to make something that other hams can use at a low enough
cost to make it worthwhile.  I think you should thank them.
