This law isn’t catered to you personally, don’t you think there are bosses or work places that call their employees after hours - it’s pretty common. I don’t mind, but I get mails and messages after hours and just answer them.
It does effect me without me knowing in some ways, but I personally feel it’s more important to help someone, that also might be stressed and decide to contact me, for some help or questions.
If the person or boss isn’t an asshole I don’t mind, but not everyone has that luxury, of having a boss that cares. Often they don’t want to contact you after hours.
Arch Linux has by far the best community, the support wiki is the most useful wiki to Linux there is, it basically covers everything. Mad props to the arch Linux community.
