While i do agree showing server messages and rendering url inks was a design mistake from the earlier than the 3.3 versions.
Electrum cannot police and control fake websites 24/7 and or browser/os exploits (all it takes is some dns manipulating to make electrum.org resolve to a fake phishing site)...
While not discussed here, the same attacks have been done to people using Electrum fork's such as Litecoin's; and the amount stolen is not negligible.
But for most of them it was simple user mistake/ignorance, or social engineering. Do not be surprised if they escalate and combine with dns manipulation done via malware (probably done already).
Good habits and secure OS are a must. If you want to make or manipulate a cold wallet, you should boot from a secure live OS (such as Linux Tails OS).
i understand how Tails Uses Linux but do you mean using Electrum on a Portable Version on a Hard-Drive with Tails Installed on it would that work?
