I hear that excuse constantly on the web if I try to correct people. And maybe it doesn't "prohibit access", but it does force me to think about things that aren't the point of the message, in order to figure out the point of the message.
I've given up correcting people. I'm old enough now that it's time to just watch people's choices come back on them. The whole world will pay for it, and I've done what I can.
I can't even get people to stop using "weary" to mean "wary". That's a whole different meaning, and there are so many people that use it wrong.
