Important difference: there are OpenWrt products that are for sale, like the “OpenWrt One MediaTek MT7981B” for 89$ on Aliexpress (https://www.aliexpress.com/item/1005007795779282.html) and there’s also merch for example: https://openwrt.org/merchandise – these things cost money and are for sure not trade-free. However, the software itself and the documentation is trade-free – made by the community.
