I'm curious what the "an open-source platform for years" in the article is referring to as far as sales/ecommerce stuff goes?

I'm friends with the author of belugajs (a libre/free/open source ecommerce/online shopping thingamajig) and while Binx [the author] is awesome, when I went to try installing it locally to test with I frowned at the Node.js stuff upon which it was built.

I've administered systems on WooCommerce too (which claims it is "open source" as well, but my experiences with it left a lot to be desired it felt much more like shareware masquerading as open source) but I still don't think I have encountered a system that seems as if it checks the right boxes, for me at least.

Admittedly, I thankfully am not selling anything personally! But still, when it comes to helping others who do sell things, I wish I had better suggestions and would love to know what others have used that they may be happy recommending.
