It seems like both the larger cryptocurrency community, as well as the FOSS community both just don’t get it. Cryptocurrency and Open Source are clearly related yet only the Monero community seems to give a shit.
FOSS community is so left-brain washed socialist that they are stuck in the money is evil and bitcoin is climate change. Crypto community is stuck in the no-adversaries mindset, as the SEC declares their products illegal but they use google, cloudflare, telegram, no understanding of any threat.

Bitcoin, Ethereum, and any serious cryptocurrency projects all champion FOSS. I dont see your point.
The bulk of the crypto wallets are not open source, including the most popular ones. And the crypto websites themselves use Google, Cloudflare, Telegram, ect
The bulk of any financial provemiders in either crypto or fiat are scams.
If you're expecting the masses to not be shit, you're going to be disappointed.
