To clarify, at the time I was aiming for the tone of Tantacrul's popular and well-received videos about poor software UX. (In particular, the MuseScore video is a good comparison; that was also an open source passion project.) Light-hearted ribbing / frustration venting mixed with genuine compassion toward the project's creator and his remarkable effort. Clearly I wildly missed the mark there. I'll try my best to avoid things like this happening again in the future.
