The lack of regulation is pretty much a goal. When a government controls or regulate a currency, your liberty is attacked.
Fraud? What are you talking about?
How is the system inefficient though? Compared to what? I don't believe it's fair to compare a decentralized system to a centralized one. Lemmy is much more expensive to run per user than Reddit for example
Fluctuations suck indeed, though they vary, it depends of the crypto
Crypto has its issues, but when used as an actual payment system, it’s a great alternative for online payments, and can give more privacy and anonymity if used correctly
Most problems are because of how Mozilla works. According to some devs, they gatekeep some contributions and they don't really act and communicate with the community like FOSS projects are expected to. They also spend a lot of money on some - useless - stuff. They're really slow to improve their software and Firefox defaults with some questionable stuff (regular pings, Google bullshit...)
The Better bird dev talks a bit about this, and you also have some other resources: https://youtu.be/ugnOM2mzgNU (I don't remember every link and everything I've seen but this should be a good start)
Brave: injected affiliate links once, then apologised for it too. Developped a search engine to be less dependent on big companies
Mozilla is spending money like crazy, just like Wikipedia, has little to no democratic system which makes people fork the stuff they make, and prefer to use the money from donation to buy trips all over the world to educate about privacy and shit while they proceed to keep adding more telemetry and BS in firefox
They also make it close to impossible to install plugins outside their plugins website, which I've heard has some strict rules and take a lot of time to approve stuff. Closed garden bullshit again
LLMs can't be fully controlled. They shouldn't be held liable
