Supporting this is making a deal with the devil because he offered you two bottles of whiskey.
Its penny-wise and pound-foolish.
I hadn't seen they were asking for a retroactive carveout! For eight years. A decade's worth of massive, post facto tax clawback? I don't know who thought this was a good idea, but they really must not love YC or Hacker News, to put those names on the public face of this...
While the law with the tax change was passed in 2017, that specific change didn't go into effect until 2022. So it's 3 years of retroactive carveouts (2022, 2023, 2024).
