How often do you submit a bug-report or feature request to a product (or library you use?)

I think I've never reported a bug to Slack or Discord - two proprietary applications. Not that there are no bugs and I did not have feature requests.

I just don't know where to report them and I don't think they will care much. Maybe there is a "support" address, but my experience with many similar companies is that the support will explain to me why it is a feature and not a bug.

I started to use Zulip, which is an alternative to the Slack and Discord, just a few weeks ago. I already found and reported 3 bugs and had 1 feature request. 2 bugs were already fixed. The 3rd one I reported only two days ago, but it was already confirmed. (BTW The same bug exists in WhatsApp and probably many other applications and it is probably actually a bug in Android and not in the applications.)

And the feature request? I'll probably implement it and send a pull-request.

Question

How often do you submit bug-reports and feature requests?

Does it depend on the project/product being open source?
