Their goal is rather important, especially after Tornado Cash developer got jailed recently. I'm not very familiar with BPI though, but it seems they previously only focused on research. Your opinion is greatly appreciated.
This is my first time hearing about BPI, in my opinion, it's a good initiative to support the BTC developers and those who build relevant tools of security and anonymity. I checked their website, not so many visitors, but I hope they will get some in future, I also concluded they don't have enough funds right now, that's why they are leveraging this moment into there own benefit.
Even if they are, I hope we will get to see good results from this association. They are planning to gather funds to support the recent cases opened against the developers of Somurai wallet. As this will be there first case as well, I did not have any data on the lawyer and there win ratio etc. to predict the expected outcomes of them fighting the case. Overall, its a good initiative, it will help new developers to come into this industry.
