The alert text can have whatever the alert author wants in it, so he could have written a long statement telling users something that wasn't "go check where you downloaded this application for more info" but rather "Emergency, you must download software from this site NOW".
I was talking about a "replacement", a new alert system if you will that sends alerts with codes not texts. A set of predefined codes can be set, each meaning something different. I don't know, something like
Code_1 = Hard Fork is going on, or
Code_2 = A critical Bug were found Check trusted sources for more info.@laanwj is the only person merging PRs....(or possibly others)
No he isn't. Stop spreading that FUD. Jonasschnelli, MarcoFalke, and sipa have commit access as well and frequently merge PRs.
I just said that name because that was the one off the top of my mind. Not sure where the FUD comes in!

My point is if you think X & Y & Z having alert keys of possibly a modified/improved alert system like what i said above (which in practice alerts people using
their code of critical issues in
their code) makes it centralized, then you should also think X & Y & Z having commit access to bitcoin core GitHub repo also makes it centralized!
