I am pretty sure that if Apple doesn't embrace decentralization in open arms, they would be left behind like Nokia, Motorola and Blackberry later on.
Nope. People don't care enough about decentralization to actually impact any company or financial institution. For years people have made fun of Apple in various ways, said that it would be the next Nokia and whatnot, but they are worth $1.3 trillion as of today's valuation. You can fit Nokia's market cap in its prime 10 times in Apple's market cap easily.
Bitcoin's market cap can fit like 10 times in Apple's market cap too.
I'm just pretty sure that Steve Jobs from heaven won't approve Apple's recent decision to remove decentralized apps like Coinbase. They would regret later on like Wikipedia did years ago by removing Bitcoin from their pages. In the end, they embraced it and started to accept Bitcoin donations.
Sorry, but how do you know that? The sole purpose of a company like Apple is to make money, and keep its shareholders happy. No one gives a crap about Coinbase's move.
