That's not really the case. Have a look at AUR or GURU repo - most proprietary software is installed by simply applying the same steps an apt, dnf, whathaveyou package manager would.
I think you're missing the point of what I'm saying. Unfortunately, words are difficult enough to produce for me, I don't have a better way to express it.
Only answering your last paragraph. You will not, ever, find a 1:1 equivalent for a few reasons, but mostly because:
Windows quircks do not have to be accomodated in Linux distros
Microsoft has very much encouraged massive software where everything is done in a single application, whereas in UNIX world the philosophy is to do one thing and do it well.
Not sure how DFS works, but with the myriad of networked filesystems available I'm sure there's an exact requirement match.
Users can be centrally managed in a myriad of ways, but the most used software seems to be following the same X.500 standard - OpenLDAP, FreeIPA, etc.
Machines can be centrally managed via Puppet, Chef, etc.
Company software is managed by having your own repo.
SELinux can be used for incredibly granular access controls, but I can't see most companies actually needing that.
To sum it up - you'll always have trouble if you're solving a windows problem in linux and vice versa. Just for a moment, try imagining a situation where you want to switch a 100% linux company to windows.
A couple things - every jump like that in resolution is about a 10% increase in size at the source level. So 2K is ~250GB, 4K is ~275GB. Haven't had to deal with 8K myself, yet, but it would be at ~300GB. And then you compress all that for placea like netflix and the size goes down drastically. Add to that codec improvements over time (like x264 -> x265) and you might actually end up with an identical size compressed while carrying 4x more pixels.
HDMI is digital. It doesn't start failing because of increased bandwidth; there's nothing consumable. It either works or it doesn't.
Iptables commands - that was needed at the very launch of wg, I've not had to deal with it for some time now.
Personal/commercial use - I'm on a completely opposite side. It's perfect for personal use, but its lack of dhcp support makes me question its capability in a commercial setting. Many providers offer it, so clearly that's not an insurmountable task, but I'm still curious how they sort out their backend.
Possible? Yes. Probable? No. LTE would work wonderfully for such usecase, but the firmware to it is never shared. Wifi would work theoretically, but the distance would get in a way. Bandwidth would go down all the way to a rounding error.
Not this one!
