regardless of whether it's technically correct(or who even gets to decide that) - the point of using language is to communicate, if you are communicating what you want then you're accomplishing your goal.

Sometimes you might want to speak more formally or 'proper' - but that's just another example of communicating effectively, by using word choice to convey the right level of formality. Or to be perceived a certain way.

Of course it's fine people are pointing out that they use the word a different way. Just saying I think the author used a clear word choice to effectively communicate what he meant to the largest number of people - even the people who are pointing out that he used the word wrong know what he was trying to communicate(otherwise they wouldn't realize he was using it 'incorrectly').
