Weird Apps on App Lounge

Hi everyone! Im relatively new to /e/os and am enkoying it very much so far.

I had a weird experience today and wanted to ask about it. Searching for “NewPipe” in the App Lounge gives one result, with very poor privacy rating.

When I searched in the settings, I found the “Show Open Source Apps” setting, and enabled it.

Then the real NewPipe showed up in a search, with much better privacy ratings. You can see both here:

My question is, where do the App Lounge apps come from and how do I investigate who is publishing them? The default result looks kind of sketchy (a tracker-ridden modification of an open source project?). Are there policies on what can be in App Lounge?
