The Stratis swap for Blitz never happened, BUT, a deal was made and documented.
Value for Blitz comes from either/or:
1- Chris Trew honoring the deal he made with Blitz 'executives'
2- Chris Trew honoring the Stratis whitepaper and making Blitz (the first) sidechain of Stratis
As much as I agree with the history you posted, Blitz hodlers will get nothing unless they take legal action now, which is very unlikely.
