Excuses for what? I myself have not gave any of these manufacturers a pass. But I'm challenging the mentally of many users having damn near temper tantrums for not having the latest security update, especially since they know next to nothing about the exploits.
And no, us PC users don't have a security patch obsession. Many like myself even do the temporary update opt out, or edit services to update manual only.
There are many KNOWN/DISCOVERED exploits of operating systems, apps, and hardware that haven't been patched for whatever given reason.
There isn't much to talk about. Some manufacturers lied about security patches, big whoop. Should it be corrected? YES!!! Are Android users under an imminent security threat, NO!!!! Now if that's cheerleading, then so be it. Don't know what type of insane panic you were expecting.
