It took them 4 or 5 years just to do this release, since it was first announced. I feel like "they just dusted off an old license" is not a likely explanation.
Probably took 5 years just to get through all the lawyers at Apple, and this is what we ended up with.
Remember, the default answer to almost any question poised to a lawyer is "No."
I'm not sure why it took so long, but I think that lawyers dragging their feet probably wasn't it. I'm guessing that they would have never announced the release, unless the lawyers had already signed off on it. I think instead, it took them 5 years to make the landing page (something like this would normally take two years, but the pandemic wasted three years of that time.)
