Most exchanges only love profits, and don't care about bitcoin at all. Take Coinbase as an example. Let's even leave out their pro-surveillance, anti-privacy stance and the fact that the sell all their users' data to a variety of government agencies, and look solely at the technical side of things. They supported BIP101, Bitcoin XT, Bitcoin Classic, Bitcoin Unlimited, Segwit2x. Basically every hard fork which would make bitcoin less decentralized and give them more control over it, they supported. They took years to implement transaction batching and spammed the network with hundreds of thousands unnecessary transactions. Then, despite being front and center supporting all the hard fork proposals which would give them more power, they took years to support segwit. Most exchanges are no different. They will promote and support forks and legislation which weaken bitcoin, but give them more control. They will list and shill pump and dumps and scams which give bitcoin a bad reputation by association, but make them profits. And they will censor transactions, contrary to the whole point of bitcoin in the first place, if it means they can keep lining their pockets.

Maybe. Or maybe on luring the never ending stream of newbies to lose all their money on altcoins ICOs DeFi NFTs whatever shit comes along next.
