According to the article, at first the accidents were "hidden" from the reporting system just because Tesla systems were not autonomous enough to qualify under the law.

But now that Tesla is trying to be more autonomous robotaxi service, they're required to report more details about their accidents.

According to the article, Tesla's competitors (like Waymo) are very forthcoming about the incidents. They are probably following the long tradition in engineering of learning from your mistakes by investigating them thoroughly and doing root-cause analysis.

Tesla cannot do this, because if they do a thorough root-cause analysis of why their system fails more than others, they will inevitably arrive at the conclusion it's due to the sensor stack being camera-only. And Tesla cannot admit that because Musk can't admit he was wrong.

So instead they're going down the path of being cagey about the details of their accidents. I don't know how long these reports take to generate but there are 2.5 months worth of reports that have not yet been released.

Meanwhile, Musk has committed to ditching the safety monitors by the end of the year, and he's not going to be able to do that if Tesla's robotaxi service is unreliable. But he's also not willing to do what it takes to make the service more reliable, which is add LiDAR to the system. So... it will be interesting to see what happens at the end of the year.
