I don't think it was due to the recent drama. (Although who knows, maybe they knew what was coming.) Mike Acton and Andreas Fredriksson left back in March 2023 I think. They posted to twitter.
Not recently, but there was a steady drain of talent. The two heads of the DOTS initiative were gone by May of this year and the CTO, and the last original Founder of Unity, and arguably largest champion of DOTS, silently stepped down in April when introducing the new CTO. Johacim's official status is apparently "sabbatical" (I'm sure he owns way too much stock and other sway to be hoisted out the traditional way).
Recently because of the drama or unrelated? That’s sad to hear as I was very excited on that effort.
