> You don't have the right to force the company to delete content [relating to you]
In the EU, you definitely do.

For a clear example of the difference: I don't have the right under GDPR to tell Apple to reach into everyone else's iCloud address books to delete my phone number out of them. Neither I nor Apple put my phone number into other people's address books; those other people manually entered that info into their address books themselves. Which makes that their data, that they created — which just happens to reference me (and which is held in trust by a third party.)
If GDPR worked the way you're imagining, then someone deleting their WhatsApp account would require WhatsApp to tell my phone to delete my locally-saved WhatsApp chat-logs of conversations with that person.
The content of a post is not personal data (in general) but the things like user name etc are. The content is not relating to an identifiable person (in general) while the user name is.
Shakespeare's poems are not personal data.
From my post history on Reddit, you'd know where I live, my age, gender, job, relationship status and a good amount about places I've been and my interests. There are already websites that collate that info from a profile to give a summary of the user. Under GDPR, that quite possibly adds up to personal data relating to an identifiable person.
What I'm saying is, in general it isn't. If you sign up to platform XYZ and make a post, in general, the content of the post is not personal data. It certainly can be. But by default it isn't. That's a misconception I want to dispel.
I can post my name publicly, but it’s still considered personal data. It doesn’t magically become a free for all just because it’s out there.
The words "Hello world" posted on any subreddit is not personal data. In this case the company could simply delete the information relating to you such as user name, IP etc.
The content you post is not, in general, personal data. It certainly can be.
Personal Health Information is only applicable in a specific setting (a covered entity). You telling your boss/friend/form about your health information does not make it PHI. You willingly disclosed that information.m, it loses its protected status.
‘Personal data’ means any information relating to an identified or identifiable natural person (‘data subject’).
Note the weight of the word “any” here.
