Just like in this discussion, youre changing the narrative deceptively.

Now they are on the phone. They weren’t before, that stage had passed.

Sure, you are now retroactively changing your intent but it doesn’t change the meaning of your words.

You say listen to what youre saying. I did.

If you said, when they call advise of the current rate, is agree. Your version seems to be past that stage. In no world does anyone think that you would be obliged to honor the quote. So either your advice is not really advice, to do what is normal and advise them of your actual rate. Or, as appears more likely, you want to leverage the mistake using their sunken cost of time after arranging a meet, knowing in advance their expectations dont match the rate.

If everyone else gets it why is there another comment calling you a LinkedIn lunatic? Its not a term I would use, but I see their point. Your comment is one of two things: A pointless comment offering no advice as of course they would clarify. A comment to say leverage it to your advantage, using deceptive tactics.

Walk it back all you want but in context its clear to me which was the intent. Perhaps you meant no I’ll will, but it reads as exploitative. In quoting for any kind of work, but especially programming based work, there is a knowledge differential. This justifies fees, but the same knowledge differential is often used to take advantage of those with no concept of the work involved.
