I'm online in cfw only for years now, it's what atmosphere is designed for. I don't even remember when I last used stock. Same for some of my friends.Awesome, I don’t ever plan on getting my SysNAND dirty. I keep it clean and stock.
As long as you don't use any nsps/xci and don't do other banwothy stuff, like cheating online, you are pretty much safe with sysnand cfw.
It also allows you to use overlays or other tools to make switching between online and offline nand much more convinient.
Yep, but you can never be fully sure, that there is nothing else that uses the serial, so better be safe by not blanking prodinfo on the online nand.Atmosphere redirects all Telemetry to a loopback address. Nothing ever gets sent by "logs". But they can still see your NSPs installed if you go online with a dirty nand.
It also redirects all creports to the SD Card, so there is no creports on the Switch itself.
