It's not really the detector that I have a problem with here, it's the "reduce vaping incidents through social influence" part. Their plan (as I understand it) is to have a display outside the washroom to tell other kids that the person in the washroom is vaping and essentially get them to quit through public shaming, which is both cruel and ineffective. If the detector instead alerted teachers privately that there was someone vaping in the washroom then the teachers would deal with it appropriately, I think it could be okay.

My brother used to vape back in high school, and punishment never got him to stop, it just made him get more creative about how he hid it. When he eventually did quit after he graduated, he chose to because he knew it was harmful.

I've used Mullvad in the past and I use Proton now. It works well for me and afaik they're a pretty good company. I found that Mullvad was better, but I'm still using Proton because the email + storage make it better overall.

I use EndeavourOS because I like having access to the AUR but didn't want to risk messing up my Windows installation by trying to manually set up Arch for dual booting (this was before archinstall was made). I like it, and I like using KDE. My only complaint with it would be that pacman kinda shits itself if you go too long without updating.

The first distro I ever used was ZorinOS back in like 2017.
