I don't know how many have tested selling digital files via their own store? If you got people who want to buy files, would they be into ordering them via "Shopify", "limited run" or whatever cart system someone is using? I have feeling as if buying files is so much more connected to INSTANT access, that if you buy album, and have to wait for 1-2 days for artists to notice new order, and send you the download link, it feels very different from automatic system?
What Magma says here, seems anomaly in underground. I have talked about it in past, but it is curious situation. As guy who comes from era when DIY ethos was strong, and opposition toward big corporations what almost automation, it has been slightly amusing to see how little criticism would be when it would be now like "iTunes", "amazon", "google", etc... Sure I have account on fb and YouTube too, but its not like I'd be most avid promoter of those or making them my exclusive outlet.
In situations where artists makes moral decisions and gets all upset if other artists may have said or done something "wrong" is not that rare. Seems more rare that perhaps those folks would compare, how bad is that, compared to former BC owner, Epic Games who was owned 40% by Chinese mega corporation. No problem being in direct financial mechanism and volunteer promotion campaign for it. Of course people can, but it is quite curious that I doubt I have ever seen others than Magma* above address the problem and then act according his principle?
