So, say I have a POE outdoor router that is TP-link. It is wired to my main router and is the network for outdoor cameras. How bad an idea is this?

Been using 10th gen kindle, 5.17.1 firmware, as my daily driver. It’s not jailbroken, use calibre server to download my alternately sourced ebooks, convert to .mobi as needed.

I looked at Winterbreak. Decided not to fool with it as I can still sail with stock.

Any advantage to a jailbreak other than future proofing against side loading being disabled?
