This is false, it's true that they opened clubs and weddings but there was a very long list of restrictions in place - from max capacity of people (not more than 250 and depending on the size of the venue), to enforcing wearing masks, to social distancing of at least 2m between people and so on. They implemented a system called "purple certificate" (a bad translation) that businesses had to follow in order to reopen. It is true that they opened things up too fast and it's also true that unfortunately, people became indifferent to the situation and didn't follow the rules as much as they needed to but it is false to say that they just opened things up and moved on, they did try to implement a large number of restrictions for reopening. What
@PRlady wrote is accurate, from everything we've been seeing so far there's a very big difference between gatherings indoors and outdoors, but even outdoors a very strict discipline of masks and social distancing has to be enforced. Yes, there might be some ways to go on with some sense of normalcy with outdoor activities, but the fact that gathering of barely 250 people indoors caused large outbreaks in several countries should be a good indication as to why conducting indoors skating events is hugely unrealistic.
I don't know the situation in Israel obviously, but I sort of agree with MsZem.
In Germany people have private parties and gatherings indoor and outdoors all the time, that have no social distancing anymore (which is allowed now, but they were already doing it, when people were supposed to have socially distant private events too) and so far there haven't been huge spikes due to that, so maybe they are not partying so wildly yet

, but I see that as a lot more risky than a public event indoor event that has assigned seats and enforced rules that someones actually enforces...Obviously you can't have normal events with normal visitor numbers, but I do think it would be possible to create something safe with like 20%viewers that wouldn't be more dangerous than my uncles half-inside garden parties

There's one arena doing concerts with 900 spectators in Germany again since mid-June, I'm sure their concept could be used for all sorts of events (apart from the issue that's it not financially making much sense to hold events like that and only artists that have a young fanbase are selling the few tickets, for now it's more like a "pilot project")...personally I find it crazier to allow nightclubs and discos (like Switzerland does) than organized concerts and sports events with rules...
I'd guess the crowd is already bigger than at Nebelhorn in normal years

I think the problems are different: financial, travel, uncertainty of planning (because obviously when there's a rise of number or a hotspot, than concerts like the one in the video would of course be forbidded again immediately and also comparable sports events with visitors).
I still think it's a bit more realistic to have small events with a few spectators inside than to have outdoor competitions with spectators, where would the rinks with spectator ranks come from, are there still any? Maybe they'd have all competitons in those half open places in Austria/Switzerland?
