--snip--
I've looked at two of his repos; they are different than the originals and he gave credit to original programmer.
If you take an existing program and change it to different things, is that a fork or a new master? I do not know...I imagine you could fork and make changes.
But is the change big enough to call it different software? Based on 2 repository which mention the changes[1-2], he doesn't made significant change.
It will be interesting to see/read about the wif500 and if they solve it.
Interesting to see, but IMO very risky to join.
