Yes. Because it'd be good to provide an alternative. Yes it's locked platform, but performance/price wise it'll be interesting to see what happens, and it's unlikely that we'll have an open alternative to it soon.

People replying "no" seem to be doing so for ideological reasons with no regard to practicality. Obviously it'd be better if it was an open platform, but it isn't, and that's fine. Whatever you think of Apple, you have a very simple option of not using their products. I don't use a Mac for that reason. But with the performance and price of new M1 machines, I can definitely see a usecase, probably not as a daily driver, but I'd still need it to run linux natively. Anyway, people who will take on such an effort (with the appropriate funding) aren't necessarily going to be working on something else if this doesn't materialize.

I don't think that asking this kind of question on twitter/hackernews is representative. Start with something and open up some way to fund it, then either continue or stop if it makes sense.
