Also, how do you know that there isn't someone performing a MITM (man in the middle) attack? FTP has no mechanism that I know of to verify that you're connecting to the server that you think you are.
It may well be that you're not a sizeable target and that no-one is interested in hacking your site, but that's just luck and not an endorsement of unencrypted FTP.
We have to put a limit to paranoia. If things work correctly for decades and there are no signs of foul play after endless real world usage, it's safe to say nobody is hacking our FTP.
It's different if you're a bank or the KGB or the CIA.

Do you drive an armored car?
A frame-less one?
It costs approximately zero to use encryption and protect against the FTP exploits, so why continue to use FTP? There's literally no advantage and several possible disadvantages. Just relying on not being hacked before seems a foolish stance to me.
I challenge you to select any FTP website of your choosing and make a tiny change to prove that you've hacked it and let me know here.
Whether or not the connection you're using is encrypted doesn't really matter because the ISP and hosting provider are legally obligated to prevent unauthorized access.
(It's different if you're the NSA or some other state-level actor, but you're not.)
And what happens if your ISP is compromised without their knowledge? What happens when it's a consumer device such as a router? Don't forget that nearly every TP-Link router has an active malware infection.
It's not just one ISP that you have to trust, it's every single intermediate piece of equipment.
Intercepting traffic is a trivial & common form of compromise, and the problem multiplies by how many different parties you are handing your data to. It is wildly irresponsible to not attempt to protect against this.
That is nonsense. The reality is that most data simply is not sensitive, and there is no valid reason to encrypt it. I wouldn't use insecure FTP because credentials, but there's no good reason to encrypt your blog or something.
The bad news with FTP in particular is that only one request has to be intercepted and recorded to have persistent compromise, because the credentials are just a username and password transmitted in clear.
Jokes aside https is as much about privacy as is is about reducing the chance you receive data that has been tampered. You shouldn't only not use FTP because credentials but also because embedded malware you didn't put there yourself.
It's not so much about the data, but protecting your credentials for the server.
