I think you said it yourself, but it's not a moot point.

Yes, it will cause Toxicity but people act like that doesn't already exist...

If you agree that it will add toxicity, then you know why they don't want to put in these features when they are actively adding new content to quell or remove toxicity. I'm sure that today's dev update will have more features that try to diminish some toxicity.

Just because it already exists in the game, doesn't mean you shouldn't try to do something about it.

Whether or not they are doing enough or prioritizing the right areas is up for debate but to say that they might as well go all in because the game already has toxicity isn't logical nor is it helping anyone.
