That's because the hype of BTC was too much that one day or another, it has to be adopted by governments, and will be legalized. So when that happens or happening now, the government wants to control it, they want to control it because that's how they can control people. But to control BTC they have to manipulate people's minds and provide them with more and more centralized platforms so that they can take over the funds of people anytime.
To keep yourself anonymous and save your funds from CEXs, new platforms are coming, for example, obfuscating platforms (mixers) DEXs, and other DeFi wallets, open source, and decentralized ones. But still, governments are targeting these platforms in the name of providing security to the people and to some extent they are at right because some bad actors are taking bad advantage of this technology. Besides BTC did not lose its purpose, mainly not because of the people after 2017, it's because of the people before 2017. Like they are holding hundreds of BTC why? Why did they not used them for p2p or other buying and selling purposes. They are the one who set's a base in the minds of upcoming peoples. CMIIW.
