I like the part where the cites techdirt article implies that the authors of the bill are tied to big tech while talking about regulation that big tech absolutely does not want. Then they scream about "correlation doesn't equal causation" while Facebook and co have repeatedly been caught admitting to trying to make their algorithms as addicting as possible.
Is it well written legislation? No. Are these arguments against it well written? Also no. Social media may not be as addicting as the bill implies, but to say that it's pseudoscience is really stupid.
