Not the person you are asking but it is getting worse by the day [1][2]. Speech policing is becoming a higher priority than dealing with violent crime. Protests are also increasing in number and frequency.
These reports both seem to refer to the UK, not several European countries.
I personally also think this should mostly not be a matter for the police to take care of, but then again do (should) dick picks and harassment really constitute the free speech you want to protect? I cannot speak for the UK, but Germany for example has had laws against gross insults since decades that have not threatened democracy; I would expect police to enforce laws, whether in real or virtual life just the same.
On the other hand, it gets murky with unwanted political opinions. Due to historic reasons, there are some things very specific things you're forbidden from voicing publicly here, because they're incompatible with our constitution, and thus don't enjoy the protection of that constitution. But in recent years, things unrelated to our fascist past have also seen litigation, which I find problematic, regardless of my personal opinions.
But given that Germany is probably the most strict European country when it comes to freedom of speech restrictions, I'm really opposed to announcing any kind of "free speech crisis in Europe".
