System76 Dev here. WRT to Amazon packages and analytics, this is not something we include in Pop_OS. All Pop_OS installs, despite being based on Ubuntu, are free of any type of analytics or other tracking types of software, outside of what is bare-necessary to have a Debian OS. We even switch out the Ubuntu connectivity checking that comes by default with our own, since this service could theoretically be used to log your IP. The server we use for this is controlled by Pop_OS/System76 (whom you need to inherently trust if you're using our software anyway; I technically have root access on any Pop_OS user's computer), and is configured not to store any access logs outside of server-side error messages.
