The problem is that the people who click on these also have lousy grammar and don't notice, don't care, or won't actually read all of the text.
There's only so much we can do if the end user refuses to think. I suspect a lot of these people will be migrating to locked down/walled garden devices soon anyway.
One of the programs I inherited once had been written by a programmer who loved alert boxes of the form 'Are you sure you want to Delete X'.
I was watching a user a month or so afterwards to notice they just pressed enter every time an alert box popped up, immediately, without reading and without thought.
Alerts on computers aren't there to be read any more. They're confusing annoyances that you just click yes to. They're usually badly written in that they tell a normal person nothing, they're without context and usually ultimately exist because a programmer was prevaricating on making a decision.
We nagged our users too much as programmers, to turn around and blame them for not thinking is a sublime irony given that we were the ones not thinking and constantly asking for reassurance that it was us not making a mistake.
Instead of using alert boxes to confirm that a user wants to perform a destructive operation, you should support undoing the change after it's done, perhaps for a limited time.
