i'm not sure what in here strikes you as alarmist. i'm actually not sure what you think you're replying to at all
like, my issue is not "the lack of full source code could have all these negative concrete side effects". my issue is "the lack of full source code", full stop
because that is a good and noble and valuable thing to share, and a game that was open source for 25 years has now been made no longer open source, by fucking microsoft
i'm aware that proprietary software can exist, and even run! i think you will find that most video games are in that category in fact. i also think source code releases are the best thing that can happen to software as an ecosystem and that doom's legacy is an outstanding example of this, and i think microsoft is trampling on that legacy
their boom reimplementation doesn't feel weird because it's buggy. it feels weird that it exists, because they painstakingly recreated free GPL-licensed community work. and why? so they could list compatibility with more free community work as a bullet point on their paid, proprietary product.
and meanwhile they don't even have the decency to throw us a real bone, like, i don't know, official permission to remix doom assets? no, they're happy to leave everyone in legal limbo, while also packaging all the free work as more stuff you can play in the official port. their free-for-all upload system tells you how much they care about wads as creative works
proton is a joke btw. i prefer for my operating system to actually have software written for it and not just be windows with extra steps (when wine actually works) (and keeps working), especially when that software, famously, used to run on linux, and in fact had to be ported back to dos because the original open source release didn't run on anything else. if you can port this thing to the switch then it cannot be that much harder to port it to linux. it's reading input and opengl! this is not difficult! and if it were open source then it would've been ported already!
none of what i said is about alarmism or threats to the modding scene or whatever. it is about open source being valuable unto itself, and about micro-thesda-zeni-kex's attitude towards the culture it is leeching off of for profit
