Doesn't discord have some pretty serious security flaws and questionable data collection policies for use as a private commercial messaging platform?

For small teams that aren't too concerned about that it seems fine. Personally my group of a couple dozen friends and I use it for pretty much all of our communication because we don't care much about privacy in that context. But for any company larger than a couple dozen folks it seems like a pretty risky choice compared to Slack/Microsoft/Google/etc.

it does, but sensite projects defenitly i wont use discord, neither slack nor zoom.
