During installation, the router sent several data packets to an Amazon server in the US. These packets contained the configured SSID name and password in clear text, as well as some identification tokens for this network within a broader database and an access token for a user session that could potentially enable a MITM attack.
Linksys has refused to acknowledge/respond to the issue.
Exacly. You basically need to flash something like grapheneos on your phone, install linux on your computer and run custom firmware on your router to even have any semblance of privacy
