So two Polonophobic trolls have a meeting of their gnarled sick minds in which the former pretends Polish sounds ugly
You don't speak Polish, so what would you know about the writing script? Go on, tell us - why should Latin be used instead of Cyrillic? What justification do you have?
There are quite a few people online who have tried to create a Cyrillic script for Polish - like Croatian, it's actually easier to use, but isn't used. If you want to find out why, perhaps look at the writing systems used in the countries which are Catholic vs Orthodox.
But anyway, have a look here -

Among people who are actually language enthusiasts, who like this sort of thing (and who study it in far more detail than you ever will) - there's a common view that Cyrillic actually looks far neater and nicer than Latin when it comes to Polish. Of course, it will never change - Cyrillic was always seen as "Eastern" and "orthodox" by Catholic Poland - which is exactly your reason why it doesn't use Cyrillic today. Likewise with Croatian, Bosnian and Montenegrin - even though it works equally well in Cyrillic.
Now - get lost, troll.
