I agree in principle that it's nice to be able to see the full conversations without clicking into a bunch of threads, but a problem that I have noticed when people use Mattermost is that they either forget or don't notice that people are using the thread feature and simply reply directly in the channel to an active thread. This makes it so that anyone who isn't looking at the channel loses track of the conversation. You could fix this by repeatedly telling anyone who does it wrong to do it right, but people simply can't make that mistake when the threads are collapsed by default.

As things are now, the thread feature in Mattermost doesn't really help that much, because if you want to be really sure not to miss part of a conversation you need to keep a separate window with that channel open anyway instead of just having the thread open in the same window.
