Between the Material You design and move to break apart the Chrome browser from ChromeOS, now more than ever, ChromeOS is Linux with Google's desktop environment.
In my desktop at home the main OS is Ubuntu, basically since more than 15 years, but I own also 2 Chromebooks laptops. I have a Lenovo Duet which i use mainly because I can run both Android and Linux apps, and it allow me to watch streaming services in offline. I would prefer to use any "gnu-linux" distro on a portable device, but if you wish to watch Amazon Prime or Netflix offline, you can only use a tablet with Android or iOs but on linux pc you are limited on web app typically, except in Chromebook which has some extra flexibility. Also I don't find invasive so far, more or less we have the same privacy settings as in Android. As benefit it's supported for 10 years for OS updates. And, in the future I may also decide to install a pure linux distro if I need.
I have used years ago different download platforms, years before Torrent, in the time of Napster, Emule etc. but so far the official streaming service provide a good offer, without wasting time. I don't think it worst the effort to download illegally ie comparing with price of Prime. I see now a tendency when the platform cost will increase and users should, in theory have 10 platforms, where i may understand the reason for people returning to illegal download. The streaming service companies should think carefully before increasing the price or creating new rules to share the cost.
