Author of this article said he finished at Warsaw University of Technology - it was always considered to be one of the better ones here.
That being said, what also strikes me is how different the thesis were back in times. I did mine recently in another university of technology in some bigger city (without wanting to dox myself that much) and 90% of our engineering theses were of very subpar quality; mine included.
Is it any different nowadays? AFAIK the goal isn't to advance the field, but to prove to the people giving you the Bachelor/Master's degree that you're able to create a "paper". Some theses stand out, but most of them are probably quite boring.
It seems to me like their tasks were way heavier. For us, most of us did basic CRUDs with some implemention twist, and our papers were your standard: do a short theoretical introduction to the domain, make a few UML diagrams, explain how it works + some code examples, then testing.
