I have periodic backups of the entire system, but I do not organize my configs or anything like that.
I only customize the install on my laptop and it is over time, I do not install different distros on it, just the same install ever since I got it. On any other install I usually use the defaults.
There are VPS services that dont give a fuck about DMCAs and pirated content. You should specifically look for one like that if this is your intent. I do not have any specific provider recommendations but you might find something useful in lowendtalk.
I dislike when documentations add sudo because what if I am root already or what if sudo is not installed on my machine and I cannot just copy and paste the lines because I have to avoid pasting sudo.
There is no such thing as a safe email client, or an unsafe one for that matter. What's important is your provider and even then email is inherently unsafe unless you use something like PGP.
I dislike general artificial intelligence. I understand that it can be a useful tool, but at the same time the thought of being in a world where people's jobs can be replaced with robots for the sake of profit and you won't be able to tell whether you are talking with a real person or not repulses me.
I have no complaints about the OS itself and I really like the package manager. The wiki is lacking tho, which is not an issue 99% of the time cause I can still check archwiki, but its something to keep in mind.
Post-install was similar to Arch and fairly straightforward, except for having to set up logind
As far as wayland goes it works the same as on any other distro, nothing Alpine specific that you should look out for.
