Notepad++ is written by an immigrant (non-french native) . In https://notepad-plus-plus.org/news/a-propos-du-tweet-contre-... , the photo says: "Please uninstall Notepad++ if you voted for the National Front" (he was assuming the xenophobic party) Each release has a message on what he believes in: https://notepad-plus-plus.org/news
I'm not French, but even if I were and were a NF voter, I doubt I would care about his political tweets let alone uninstall the software as a result. ...as someone not involved in that political fight, I slightly worry that this will serve as a distraction for him in future project development, maybe lead to a broken release or a dev path and force me to look for a new tool - zeal often crowds out focus. ...but hey,…
I think your opinion here is a commonly held one, which I find increasingly frustrating and bizarre.
I personally feel that work and politics are by definition inextricably linked, and attempting to separate them as some sanctimonious attempt at taking moral highground is naïve (at best, insincere at worst). Which makes the use of the epithet "immature" here particularly ironic.
