I believe the fact that Polish uses the Latin alphabet (with a small Slavic twist to express the extra sounds) meant it was much easier for Poland to align itself westward. I think the average Pole is much closer culturally to the Western neighbours than to a Ukrainian or Russian (maybe apart from cuisine).
As I am fond of saying: "The good news about Open Source is that you've got the source code; the bad news about Open Source is that _you've_ got the source code."
That is, you may well get sucked down a rabbit hole in order to accomplish a simple task.
