I’ve never actually come across a better maintained project personally. It is incredibly thoughtfully developed with a high level of attention to detail who have successfully shipped a huge number of major improvements in ways that made sense.

There is a premise in the post that implies Flutter is poorly maintained and that’s just not a commonly held belief by the community at all.

As I hinted to in another comment the particular person behind this is a bit of an oddball and I think there may be other reasons that drove this decision in the first place in addition to the ones he gave in the post which for the record I’m sure there are some things he wishes were prioritised differently but this fork seems kind of very “him” rather than a popular position that people were begging for.
