A large amount of energy is wasted on "infighting" where people spend significant effort on attacking projects that, seen from a distance, are actually allies¹.
Or where people dismiss the entire project because it's not 100 aligned with their view of perfection².
Or, indeed, where people who don't even use or want to use a project, spend significant effort to discredit this project.
¹ an example is the enormous amount of effort and campaigning within the "mastodon" community against projects like bluesky or nostr. But also gnome vs kde, Ubuntu vs Redhat, Etc
² an example is Opensource software being discredited because they use GitHub, or host on AWS. It's Patagonia being discredited because they use plastic. Or Fairtrade coffee being dismissed because it transports coffee with trucks and ships burning oil.
