I wrote a bad Python script that I use to encode WAV files, upload to B2, and generate an RSS feed. I host my MP3 files on Backblaze B2 and the RSS feed on GitHub pages. With my usage, I stay in B2's free tier.
While I agree that most technologies can be used in both ways that are good and those that are evil, some technologies "appear to require, or to be strongly compatible with, particular kinds of political relationships" [0]. I find it reasonable to say that a technology may be more or less moral/ethical depending on what it encourages.
