It has been said thousands of times, but... Anything automatic can automatically bite you.
IMO, @Karsus has reason to be concerned. Yes Linux is robust and seldom hacked compared to Win, but as @Watford pointed out, this could create a/another backdoor for hackers.
Hackers skills have improved as the software improved. There is hardly anywhere they haven't been and undoubtedly numerous places we don't know they have been. Many unexplained events occur to create havoc in our lives.
I think the most troubling item I read was from the Datamation Site
"I do have concerns about potential unforeseen security "gotchas" yet to be discovered. Not because of the X11 comments above, rather due to the automated approval process for snap packages."
I hope they are mistaken. If it can be automatically approved where are the human checks and balances?
I am not a programmer. I am barely a user. I wouldn't know a snap if it bit me on the ankle. I just know that automatic is good as long as it works and it automatically has a chance to break more than itself.
Last, snaps seems to be a Ubuntu "thing". Why would any other distro jump on the band wagon? Sure they can, but why?
