except what stops apple and google from building basically the same features and also having full control over them? and you bet that people would rather use apple <whatever> than shady crypto scam <whatever> if they really want to. the takeaway is that crypto is going to change practically nothing and produces nothing of value anyway.
Nothing stops tech companies from building crypto wallets or services that hold custody over users funds, a lot of them are already doing that. Building a new blockchain where they fully control the network and its features is harder.
look at atm cards. thaeres like 4 major players globally, controlling everything. I'm not talking about big tech building crypto wallets, I'm talking about them building features similar to what blockchains can do- fake DAOs, fake NFTs etc. the point I'm trying to make is that the end result of all these features doesn't inherently need a blockchain if a major player wants to build them
