I don't think this is a reliable indicator. When you take a look at the target market of discord, it becomes pretty clear why no one really cares about the data being decrypted.
The main audiences for discord are gamers and massive open communities. The first group is unlikely to discuss any sensitive topic via discord and it's not unlikely that a lot of discord users even stream their sessions publicly. The majority of conversations are likely to be game-related and not of private nature.
For the huge open communities, encryption doesn't help to improve privacy when everyone can join anyways. If you want to grow a big and healthy community where everyone can join, the 3-letter agencies might as well join the voice channel rather than being the mitm.
I haven't met anyone who is using discord as an alternative for WhatsApp, Telegram, etc., from my experience, discord is mainly used for on-topic discussions rather than private communications.
And as other comments suggest, there are legitimate reasons why discord might want to decrypt the communications on their end. Plus, I have never seen any claims by discord to be p2p encrypted.
There is a massive political community on discord, there are other groups on there such as dooxers, trolls and irl shitposters and other odd groups that are doing naughty things.
