Re: "Snap!" But is Canonical really --
-- the Guardian of the Universe?
I don't think that's how Snaps work. If I read correctly with these coke-bottle glasses of mine, then the application devs are responsible for maintaining their product's Snap. For example, Firefox will maintain the Snap for it's software:
"'We strive to offer users a great experience and make Firefox available across many platforms, devices and operating systems. With the introduction of snaps, continually optimizing Firefox will become possible, providing Linux users the most up-to-date features,' said Nick Nguyen, Vice President of Product, Firefox at Mozilla." (Linky)
The question is not whether Canonical will be a proper gatekeeper, but rather will the devs responsible for your IoT router issue new Snaps in a timely manner? I would decline to hold my breath on that. Given current vendor dysfunction, a router may indeed become a "rooter" in the Australian sense -- with or without Snaps.
