Funnily I saw the playthrough of your game in YouTube and it really looks like a labour of love. As the guy who did the playthrough suggested, still need to buy it as a thank you.
Or is that another game with a red button? The maker of the game I'm thinking about wrote a comment on YouTube
He basically forgot about the winner, has to be reminded and years later the guy received something that was way off from what was promised.
You can find a much better and more accurate description by searching, but maybe that's good enough.
This strategy might have only worked with the destruction of cities by nuclear weapons in Japan.
The resolve of the German population was not broken by the bombing of civilians. If they wouldn't have hit the military production capabilities and invaded with ground forces the war would have dragged on much longer (and Germany lacked vital resources in their territory, unlike Russia).
So even if your suggestion to bomb the civilians wouldn't be quite reprehensible by itself, it's extremely unlikely that this would end the war on it's own.
Just look at the numbers of soldiers Russia has lost, this didn't seem to faze the support of the general population so far either (families and friends if those who died it who were severely injured).
The main problem with all the alternatives is for me (as a hobby photographer) the lack of models on these platforms. When looking for models, I find them on Instagram and no other platform. As with WhatsApp the majority of "normal" people have decided to use that, so if I'm telling them to contact me on Signal, they shy away from that (and stillI I refuse to use it as much as possible).
So looking at Signal, it's free and very, very close to WhatsApp and yet still people don't want to use that. Getting them to use pixel fed would be much, much harder.
After driving my current car with Android Automotive for over 45.000 km I can only advice to stay away from vehicles using it
Android Auto (with the car working as a display for your phone) is really nice. AA OS is not.
