Open source comes with a cost to the developer. There was an interesting discussion about it on HN a couple of months ago.

It's possible to set up your repo to have issues disabled, which will get rid of the majority of FOSS's costs.

When it comes to privacy/security tools, it makes sense to make it open source, since they usually are given an insane amount of privileges to modify your machine.
