Agree with your analysis, just pointing out that Phoronix forums have always been like this, or at least the tendency is to insult each other. Their culture is more toxic than any other Linux forums I've seen, maybe besides /g/.
My uni groups are big enough that they wouldn't reconsider just for one person, group chats are mostly on WhatsApp, with some on Facebook. I managed to convert one person into using Linux though, so I consider my time at uni an overall W.
On my personal computer, zoxide, fzf, fzf tab completion allow me to jump around anywhere quite easily, I still use exa/cd for the most part. Look into this if you need more visualization. I still use a GUI file browser from time to time.
Oh my server though, I still use the default shell, so yes I just memorize where things are. But a trick is to allow for a large history file, and I use the command history search (Ctrl-R) because I tend to run the same things constantly. My setup helps too, I run things in docker, and have a data and a config directory, things go into each accordingly, and I bind mount those directories instead of using volumes.
If you edit config files a lot, in vim or nvim, :bro old will give you a list of files you recently edited and you can jump to them by inputting a number.
If you want some cloud syncing but also want privacy, then you will have to self-host, or pay someone to do it for you. There are some free tier Nextcloud accounts, but quite limited in storage. Disroot is one of them. If you do end up self-hosting, there are really good budgeting stacks out there:
My partner and I use Actual budget, and I can recommend it.
For any of these services, you don't even have to have a server running 24/7 if you don't add transactions live. If you do it once a day, just boot up the Docker container, store your stuff, and go about your day. But if you want constant access, you'd have to leave the server running all the time, and to access from the public network, then I recommend Tailscale.
I think this is the solution to the problem OP is having, the same thing happened to my instance since I used configs before this was spotted, after changing it to match this commit, the subscriptions work again, but only new posts come in.
I've been waiting on this issue the day it was posted... It doesn't bother me as much as I have a second vertical monitor so the flashing is at the edge of the vertical one, and it's definitely reduced but not gone away. Coupled with these recent driver updates, my X server just gets slower over time (not in game, thankfully).
Nvidia doesn't even have to go FOSS, they can just go OS, and this issue could probably be resolved by now due to increased transparency of what the f is going on with the drivers, as well as better collaboration between kernel developers and driver developers. Who knows what they're attempting behind the curtains, 3+ releases since this bug was filed and still not fixed.
It could also be for patenting reasons.
