Admittedly, I don't know about Telegram. But I would probably guess the distinction is still there because if I had to guess Telegram doesn't advertise those groups, you have to look for them, which decreases the condition of "audibly hearing the discussion." Where as Parler being a social media platform first wants to encourage the network effect and engagement among it's users, thus encouraging this open discussion and connection among potentially dangerous elements. Again in my non legal estimation of the law (not that I think anything I'm currently suggesting has been tried in court).
