I didn't blame anything on you. Here there is the fact: there is an army of Obsidian users that everytime someone mentions FOSS e.g. "I like Obsidian but it is not Open Source" they reply with those strawman arguments and sometimes link that forum thread with a reply by an Obsidian dev.
Now, you can release Obdisian with whatever model you want or have any opinion on FOSS. The point is not confusing people, specifically making them believe FOSS is a totally different thing.
