The original example was 10k for a "private university via distance learning", which I assume won't be free in Sweden either. FWIW, I paid 250 euros per semester in Germany, most of which was for the public transport ticket.
Private universities don't exist in Sweden, at least none that offer CS degrees. There are a few MBAs for which one has to pay the full price but they are usually only attended by professionals and charged to their employer.
Same in Poland - all of the best universities in the country are public universities and are free for everyone. Private ones have a reputation for being very very poor and something people sign up for just to get the paper saying they have "a degree". Even then, they cost something like $300/semester so if you really need that paper it's not that expensive.
