this is a form of ecstatic glossomania, wherein the speaker is so overwhelmed by their emotions that they lose control of their speech; they are effectively babbling, like a child, in sheer ecstatic expression, channeling the feelings without much temperance. many such cases.

there's nothing inherently wrong with this, either. there should be space in society for ecstatic experiences, ideally guided by a shaman. some religions provide for this, such as pentecostals with their speaking in tongues.
but this does not belong in the professional sphere.
consider, perhaps, how inconsiderate it can be, to present yourself illegibly, forcing others to work harder to parse your message; do you not care about your content? is your form more important to you than the time and energy of your counterparty?
standards exist for a reason
to claim that being expected to control one's self, temper expression to fit affect within standard norms, is harmful or oppressive, is a bit of a reach. this is a childish social regression, another instance of the pendulum overcorrecting.
maybe your personality doesn't matter.
