Edit: I would also add that, based on the specific software/business, the problem with "rug-pulling," as described by another user here, is a real thing. I think that the reason Obsidian doesn't get hate, while being closed source, is that they are at least predictable and honest about their strategy. Their pricing is fair, and development and business plans are openly communicated. It's silly to be angry at a firm for wanting to be closed source, but if they start out pretending to be fully open source and community-motivated, while receiving lots of coding contributions, then suddenly do a rug-pull by removing features from the community edition and paywalling all important features, that is something a lot of us are going to be annoyed by.
