Press releases give a very highly distorted vision of reality. Stick to real investigative reporting, not self-generated hype. As far as engineering and science education in Poland goes, the two things students unanimously gripe about are poorly funded practical courses of little didactic value, and poor partnership between engineering schools and the business/industrial community, both of which limit employability.
Also, most of the best Polish engineers go West. They can't afford not to. For example, given the same qualifications, experience and position, a single engineer can easily save up $50,000 a year in the States. They wouldn't even make that much in total in Poland, and wouldn't be able to save up that much in five, or even ten years. You're not going to make a Silicon Valley out of someplace that suffers from massive brain drain.
..now you have lost me...
Winter in northern Europe is quite a shock for people from warmer climes. Every year, I see the despair and horror on the faces of the foreign students in mid-October when the first cold snap arrives and they are told that they ain't seen nothin' yet. I usually take at least a couple of them shopping for proper winter clothes. One student I knew from Kenya seriously thought the world was coming to an end. And by the time April rolls around, they are totally sick and tired of the cold, and not at all eager to repeat the experience. Many foreign workers from warmer countries won't stay through a second winter unless the pay is very, very tempting. Especially if they have family. Students might put up with it for a few years, but working stiffs won't, unless, again they are amply compensated.
Also, working in an outsourcing center ("murzyn polowy") or an "internally outsourced" center ("murzyn domowy") means that your essentially outside of the corporate mainstream; there's little chance for advancement in the outsourcing center, and little chance that the corporations who contract with the outsourcing center will notice you. Even if you work at a corporate location in Poland, you're often not fully integrated into the global corporate structure, and advancement is difficult unless you get a transfer. Until then, you're just boxed and labeled as cheap labor for boring grunt work. A common and major complaint among Polish engineers working for western companies in Poland, many who took the jobs specifically because they thought the corporate ladder would be open to them. They feel cheated when they find out it's not.
