From the perspective of someone who isn’t currently in the “Bad If Not FOSS” mindset, this image really gets the impression backwards. To the average user who doesn’t appreciate the user-unfriendly klunk and jank that is inherent to FOSS interfaces, it really feels like the image should depict a bunch of FOSS Teletubbies being intruded upon by a competent Power Ranger.
I used to be a FOSS guy. And then I realized I valued my time and sanity way too much to spend more time troubleshooting and nudging my software into just working normally than I did actually using it.
FOSS software as the underpinning of the platform that is then accessed by a closed-source client is, ultimately, the best circumstance we could ask for. Clients are what the user actually interacts with. If that experience is more engaging and approachable, you get many more users on the platform overall, without threatening the sanctity of the freedom of the FOSS platform it all runs on. There is no one authority to make unilateral decisions to derail the platform, while still offering a more welcoming public face. If you can’t understand that, or don’t care to recognize it, that you’re content to let the platform wallow in obscurity.
