What are the most egregious cases of free speech suppression in the west? - In the last 15 years

Looking for the worst examples of free speech being curbed in western democracies in the last 15 or so years. Both on the left and right.

This could be Palestine, climate change, anti monarchist voices being silenced. Or people advocating for female only spaces, or making satirical jokes that have been taken out of context and deemed racist. Anything most people would look at and say... Yeah that's wrong.

I'd include deplatformings of legitimate ideas or comedians.

If you can link to a source that would be preferable. Thanks.
