The same also applies to other things, like tools.
I'm working in Java ecosystem and there's a noticeable trend to look down on people who don't use IntelliJ Idea. I've recently joined a new project and I was strongly encouraged to use it. Therefore I'm currently 3 weeks into my 4th attempt over past 10 years to switch to this tool and it simply doesn't work for me. I've been using Eclipse since around 2007, know it very well and it gets the job done. I will not claim that it is better than Idea. I just don't think switching would give me enough return on investment. Especially now, as I'm still learning the new project.
Another reason not to switch is to avoid becoming dependant on an expensive tool. My current team is using Ultimate edition and I've noticed that they are really depending on the extra features.
Thanks. Plain Wireguard is an option I'm considering, but it's also considerably more hassle to configure and maintain, especially as I connect more family members to my network. Headscale also has an extra layer of security in the form of ACLs, which I plan to use on top of basic firewall configuration. I do connect my personal machines with Wireguard, but I use one family member as a Tailscale/Headscale test subject.
As for SELinux, I've gave up on it already. It caused me so much headache over the years I disable it with a kernel parameter by default on all machines.
