I think this is the real debate. Since when did Browsers get into the account/password storing industry? Isn't this why we have browser extensions in the first place?
The answer is also kinda obvious. It started it as a matter of convenience ("I'm too fking bored to type out my long-ass password" or "I have so many passwords, I can't be bothered to remember them all" or "LastPass? What's that?") and has remained so till date. In fact, it will continue to do so until a zero-day exploit appears that can uncover these plaintext passwords, which, judging by current events, doesn't seem too far away
