Literally every single German old enough to remember life in the DDR that I know (which aren't exactly few - I am German) recounts that time with terror.

Define "that time". The DDR suffered a state and economic collapse shortly before it was annexed, due to general instability of the Eastern Bloc, particularly the liberalization of the USSR (which also caused its collapse). Anyone who was a teenager would have lived through something scary.

If you don't know any East Germans who preferred life back then then you have likely only spoken to people who weren't adults for any appreciable amount of time in the DDR. Or live in a very strange bubble. I have met plenty and I'm not even German.

In my entire life, I have not met a single person alive back then who wants to go back to the DDR. There's no notalgia, only painful memories.

The fact that you're literally unaware of Ostalgie suggests you are generally unaware of anything about those who actually lived in the DDR. To have lived as an adult there for, say, 20 years, they would nedd to have been born before 1950. How many 70-90 year olds do you hang out with? How many who were kids and teenagers in 1985, i.e. now 50-60 years old? I had to make an effort to meet such people, who were younger when I did.
