The key thing is,
of course people are getting vocal - and vocally annoyed! - at crypto-bros, given what cryptocoins have brought upon us over the last years:
- a shortage of all components used in building PCs, starting with CPUs, then GPUs, then RAM, then HDDs, and back to GPUs. Simply because scalpers and shitcoin miners could outbid everyone else.
- People getting hacked left and right (particularly blue-checkmark accounts) on Twitter, Youtube or Facebook to rename them to Elon Musk and promise crypto airdrops
- the amount of corruption that has been necessary to enable said hacks. "SIM swapping" attacks used to be something nation states did against top-of-wanted-list criminals, not something that could be bought on the darknet for a couple hundred dollars
- the loot of said hacks ending up to fund Iranian or North Korean nuclear terrorism programs
- the amount of large scale hacks made only possible by Bitcoin and friends providing a relatively easy way to launder money, in particular ransomware
- an awful lot of "stars" peddled NFTs, ICOs and the likes and let their fans hang out to dry when the hype collapsed
- an awful corresponding lot of friends and sometimes family that got lured in by shitcoins, actually made money and now peddles shitcoins instead of crap MLM products to everyone whose ears haven't fallen off since long
- all the "rug pulls", "hacks" and other instances where serious amounts of money got stolen or vanished into thin air
- artists getting their works minted as NFTs without authorization
- people buying up coal power plants of all things to mine shitcoins
- instead of delivering the promised "there are no banks and taxes!" world, all shitcoins (obviously... as everyone predicted) ended up depending on centralized institutions like exchanges, large mining pools, auditors and the likes, especially once governments around the world caught up with developments. And to make it worse, many of these institutions end up with lesser consumer protection than banks! Hooray!
The only positive contribution that cryptocurrencies brought to the world was that people had a safe way to pay for and order illicit drugs, as taking out shady dealers and cutters reduced the amount of contaminations. Oh and maybe kick some arses at Western Union into reducing their rip-off rates for international currency transfers.
