I clicked on the article in order to understand the reasoning behind this change, especially at this time where the cold weather is especially harsh for a portion of Ukrainians without electricity/heating:

Announcing his signature on the bill, Nawrocki, who is aligned with the right-wing opposition and regularly clashes with the more liberal ruling coalition, claimed credit for pushing the government towards ending the “unconditional privileges” granted to Ukrainians.

No reason. Just another fascist undoing policies put in place by human beings with a bit more sanity.

Isn’t he a Trump ally?

What, this guy?

The whole of the guy's party is ultra pro-American.

Oh I didn't know. That explains a lot.

Sad.

Unfortunate trend.

Switzerland now doesn't grant the full special status if you are from a "safe" region in ukraine, even though attacks are common there.

Unsurprising. Ukrainians have become a large minority, and even though they're the ideal immigrants for far-righters (white and christian/atheist) to welcome, they get duped instead (and for what? They help the economy as much as other sociological groups!).

Because they're easy to blame stuff on.
