So Android Kodi is still safe?
I know this is late as hell but feel this needs said.
Kodi, not an application that I actually like all that much, has always been save to use. All the repos that offer "improvements" for Kodi are not trustworthy in the least.
I can't say I personally have anything against "piracy" of stuff on the web but it is a criminal offense. But being stupid enough to use Kodi as a tool for such is just that. Stupid.
While it doesn't appeal to me, I keep trying it about once a year and removing it a day or a week later, the project has my admiration. They do a good job of what they are doing. People misusing it with those "improvements" are giving it a bad name and could, possibly, destroy the project. Don't do that.
If you feel you need to - at least use your head. First get those "improvements" is a safe manner. Download them with a live session to a stick and then - very carefully and completely check them for malware.
And then if you use them use them with at least a good vpn and preferably the tor network. Being prosecuted (or persecuted if you prefer that term) is expensive and causes long term harm to yourself. This needs taken into consideration as a cost in your calculations.
In my opinion there is very little out there that is worth the risk but people do it all the time. They need to think on it a bit. May come up with an answer that is very different than mine. Fine with me. But think about it.
