I’m going to take your point to the extreme.

It’s only open source if the camera that took the picture that is used in the stock image that was used to create the texture is open source.
You used a fully mechanical camera and chemical flash powder? Better publish that design patent and include the chemistry of the flash powder!

I haven’t bought anything from Walmart, Amazon, or Target in over a decade, probably close to two. Sure it costs a little more, but I try to source as much as I can from Costco which helps balance but otherwise I do almost all my shopping from local groceries (surefine, tops) and local hardware stores (franchises I know but generally locally owned)
