Firstly, the ones in question are ETF companies, not commercial banks. There's a difference.
Secondly, what do you think anyone can do about it? No one is in a position to prevent donations. Nor should there be anyone arbitrarily deciding who can give money to who.
bitcoin is its own economic ecosystem, if devs cant work out how to sustain their own life using bitcoin, with bitcoin.. thats on them
when it comes to "following the money" of devs, yes we should scrutinise the developers governing the network. we should not be blind to it (unlike what doomads cult wants) we should scrutinise and review them and look at their intentions for the network and what is actually controlling the decisions of the networks direction (unlike what doomads cult want)
funny side note: doomad and i agree on scrutinising CSW sponsorships/money influence of a crapcoin.. shame he doesnt want the same background checks of bitcoin governance
doomad wanting the core devs to be not independently reviewed via outsiders, nor scrutinised and nor talked about when they make moves that dont benefit bitcoiners but do benefit fiat loving people trying to scam and defraud users via recruiting people to other networks for the purpose of getting ROI for the sponsors of the devs.. well thats on doomad and his cult of other network adorers that some core devs think the agenda of bitcoin should move over to
analogy of US government
doomad is the guy that wants trump to run the US and not want anyone to ever suggest having elections after he gets into power, and then suggest no one should ever question his decisions.. thats tyranny
doomad doesnt want the US run by multiple states where different political parties all run within the government with elections that change to over time, he doesnt want consent of the masses, he doesnt want scrutiny, transparency
doomads view of open source is to publish Trump laws for all to see, but doesnt like outside input of draft/pre-law discussion that could veto a Trump law made by trump and his family. but any law made by other states or other candidates should be told to move to mexico or canada and try out their pledges there
(to doomads usual responses about me using american terminologies instead of british(as his way of evading the point): yes im british but majority or readers of this forum understand the american political/economic system more than the british system hence using american analogies make more sense)
to put it in british terms. doomad would love it if britain remained in the david cameron tory era and had no elections after that, tory forever and never scrutinised
