It’s open source. The only way to compete is on your merits in open source.
If you want another UI to flourish, clone both it and A111, copy and paste the bits from A111 you’d like to have in yours (with attribution) and push it up along with any features you personally want.
That does require developer time, and developers may converge on a popular implementation with good tests and lots of features as it’s easier to contribute.
The bottleneck isn’t really the community though, it’s the developers.
