It was a month ago so I don't remember specifically what I used as a source at the time, but this source says:

Jordan and Saudi Arabia have recently closed Al-Jazeera’s local offices, while the channel and its affiliate sites have been blocked in Saudi Arabia, United Arab Emirates, Egypt and Bahrain.

It's an article from 2017, so maybe there's been changes to that in recent years. However, OP is the one making the claim that western democracies are blocking Al Jazeera so you should probably ask him for further support of that.
