Has your opinion changed on that in the last few years? I could have sworn you were on record as saying this about foundation in the past but I couldn’t find it in my links.
Sometimes I look at what people say about FDB and it feels like... folks are putting words in my mouth that I don't recognize. I was very impressed by a short phone conversation with their engineers ~12 years ago. That's good, but that's not, like, a substantive experimental evaluation. That's "I focus my unpaid efforts on databases which seem more likely to yield fun, interesting results".
