Actually, it became very difficult to find reliable, and trusted information. Frankly, who cares about trailer videos or cat videos. My real cat is enough - sure, you have to clean its litter box too, but it means you actually care.
Sure, there are some reliable and trusted information around. The issue is to find them, and evaluate their reliability. Actually, only people with enough first hand knowledge of them can asses their reliability - most can only hope they are. Look at Wikipedia - how many misleading information it hosts? StackOverflow? Lot of litter there too. One million stupids don't make a clever one. Knowledge is not "democratic".
Sure, it had amplified the communication ability - but a global soapbox was really what we needed? Collaboration too may not always be positive - you can collaborate for nasty ends. It won't be the first time a new communication and collaboration platform is used that way, especially when most users are unaware of how much they can be manipulated.
What we see now it's not a clash of cultures - it's the deliberate exploiting of ancestral fears exactly to stir a clash.
Every democracy has a level of "censorship" - defamation is an issue that can mine the very foundations of a democracy, and evidently breaks fundamental rights. And we unluckily undergo several periods when hate speech turned into real massacres.
Comparing it to China censorship which is built just to ensure a ruling elite can't be changed, is really specious.
