Your suggestion that it is malware is misleading. Malware is “any software intentionally designed to harm, disrupt, or steal data from computers”. I sincerely doubt that was the author’s intention.
Everyone in open source is trying to write good software and the definition of good is subjective depending on overall design, features, ease of use, quality, and performance.
If an open source project is missing a feature, go build it. If the project maintainers don’t want it, fork the project. Be the change you want to see in the world. That’s the beauty of open source.

The feature being: don't delete my data belonging by another program? It's kind of too late once deleted isn't it? And now even that other program cannot use the data either.
