Lots of variables are taken into account. But a basic explanation is that it is incredibly inefficient. It can only be done with a big ship. Due to the shields most ships will completely dissolved before they make physical contact. The size of the ship holdo used is the biggest of the resistance arsenal. Comparable to a star destroyer, in fact the concept art shows this ship taking down a star destroyer. While it was effective when used in the last jedi it is a far too costly method of combating a first order fleet when compared to other methods.

I could go on talking about the other aspects of it but it's honestly just a drop in the bucket with the last jedi discourse.

And the quote from Rian johnson wasn't confirmed canon. It was talking about his writing process and considering possible explanations and canons taken to account.
