As others mentioned - logrotate is available as an option, since the system one is more preferable for many. As per reboot handing - it's available via "pm2 startup" script.
I work with NGO (property law) and couple of months ago we were awarded a grant for ads, around €2000/mo. Initially, I was pretty surprised with how generous this was, but later realized that it's both - a way for Google to brag how much they help "good causes", but most importantly - to raise the ad costs for others.
All in all - we made a few spammer operations less profitable, a couple wealthy assholes were angry about us helping people defend themselves and we brought quality traffic to the website and FB group. Thanks Skynet!
You are correct. LTT's coverage mentions that while it's not loud, it's a bit unpleasant due to high frequencies. Although things might get tweaked with case design probably. Regardless, I am super excited about this tech.
I'd say it's about making gameplay less rough for players. It's one of the first things I notice when checking out GTA inspired titles (especially from indie developers) that the streets are realistically narrow, while in GTA titles you can easily fit 4-5 vehicles in 2 lanes.
