All the major miners are welcome to attend. There are several people from China attending.
Claiming it's a "whitey" audience is both incorrect, spiteful and bizarre. The release doesn't list the name or race of the attendees other than a handful of them.
What specific person who should be invited do you think was excluded based on race, if anyone?
Of course the major miners are welcome to attend but they won't because they don't have to because they're in control. Hell, the devs couldn't even set the block size where they wanted to because the Chinese mining consortium said no.
Look at the list of names attending. It reads like a western golf championship with the token "black guy" attending. Just like the western golf championship, it's not racist because no others choose to attend and the token "black guy" that does attend is winning all the games.
If you want to really discuss the future of Bitcoin, you need representatives from BTC China, OKCoin, antpool, F2Pool, BTTC and HaoBTC. It wouldn't be a bad idea to include an invitation to representatives of the Chinese Ministry of Finance, Chinese National Development and Reform Commission and the People's Bank of China. They might not send a representative but it's a nice gesture none the less. Since TBF self destructed in a pool of corruption there really is no other group taking the lead concerning governments.
The people on your list read like the United Nations of Bitcoin. Just like the venerable dignitaries of the United Nations, they are important people, certainly, but powerless and not really in control of anything.
