Yes you could, however, this isn't only about the trustworthiness of your claim. More importantly it's about the trustworthiness of the longevity of the data.
Twitter can remove a single post or turn off their servers and your prove is gone. That's not so easy for a BitCoin transaction. Once it's added to the blockchain it's there for as long as anyone is running a bitcoin node.
But that's kinda centralizing it. What if twitter shuts down? What if twitter's DB is compromised? With bitcoins, it kinda makes all this impossible (cryptographically) and making it super decentralized

Couldn't I also publish the checksum on Twitter? Although it's not decentralized, it's probably equally trusted in the eyes of the legal system.
