You're still not getting it.

Taking the course is not a negative signal.

Putting the course on your resume, as if that conveys useful information, is.

I think it's clear that you are not getting it, that is just your opinion.

Are you a hiring manager? A you are hiring manager of the whole IT industry?

Even in this thread there are many that have successfully landed great jobs with certificates on their resume.

OK, good luck.
