If you read the ToS it also is very specific that it's not your data.
Check the ToS you don't own anything on Discord you even transfer copyright for every word you type. What even is your argument here? That it would be nice otherwise?
This is blatantly false. https://discord.com/terms under "your content" claims that I give Discord a forwardable and nonrevokable license to do anything with my content, not that I transfer copyright.
Do you know why Google Hangouts and FB Messenger provide a data export that includes others' messages? Do they base it on a different interpretation of the law, or is there some other reason for them to do so?
Citation for this? It seems pretty intuitive to me that messages sent to me are considered to be "my data", and your claim doesn't seem to be consistent with the overall theme of the GDPR...
At the very least, there's a distinction between personal information such as your name and address (which the GDPR regulates the collection of), and non-personal content like anonymous usernames and sent messages.

They have a license on everything sent AND they can use it to reproduce, publish, etc. So they very much can create the functionality.
> When I request a copy of all data Discord "has on me" I get only the messages I've sent (which is borderline useless), and I am only allowed to do that once a month, with a days-long waiting period.
What he is trying to paint as a broken feature is just compliance to GDPR and with that you only get your data.
Full comment because context is important.
The first part of the comment is explaining that there's missing/broken functionality. They're trying to export data and that's missing. What Discord has, which could count be used as that feature, is requesting a copy of all your data and THAT is broken for the use case because it's missing the messages of others and, even then, it's once a month and there's days-long waits.
