Honestly, I fail to see the problem, if I had to run `ls --no-awesome-ls-pro-upgrade-msg` once when I installed it the first time. And if I did not like it, I could use one of the alternatives to `ls` or build my own. In LibreOffice I have to click a "Don't show tip of the day again" every time I install it on an new machine, and personally I have no problem with that. If I had, I would use something else. Zsh asks me to configure it, first time I run it. I find that slightly annoying, but not to the extend that I would even consider complaining, sending a patch, or using an alternative. But I assume you are aware that your comparison is really not valid: Parellel is not limited in features - you do not get extra features by paying/citing. What you are doing is keeping it alive. Also, if you really do not like the notice, why not just pay for it? Are you opposed to paying for free software? And if so, how do you suggest developers of free software make a living? And why are you not actively doing that for GNU Parallel, which you clearly have so strong opinions on, that you are willing to spend time complaining but not willing to ignore (and use another tool)?
