Soviet Union operated under state atheism that would turn churches into warehouses, barracks, or outright destroy them as seen
here.
Germany's anti-Catholic laws can be dated back to Otto von Bismarck (so basically before the institution of unified Germany even existed), which included disbanding numerous religious orders and confiscating church property, which effected Polish majority areas the worst, as the Polish catholic church was the strongest advocate for Polish rights and independence as seen
here.
By contrast, the Ottoman Empire was very liberal as once it took Constantinople, it's first instinct wasn't to dismantle the orthodox institutions, but to maintain them, even assigning Patriarchs that would help govern the country, as seen
here. Of course, Ottoman history has a lot of instances where Christians were oppressed, but there wasn't the same systematic destruction of church institutions as with previous two examples.
