I belive you are correct but it's stil a bit shady and can happend again. I do recommend testing deepin om RebornOS which is a fork of Antergos. Reborn OS has a great and friendly community. I used deepin for a few monthes before I went back to kde and then back to deepin for a week back to kde and now i am rocking gnome for the past month. I dont really like ubuntu based OS as they most likely will use snaps which I hate since they are slow as a snail.
