People misunderstand one thing; The 48 hours is a start.
There are subs who immediately blacked out for indefinitely (r/videos and r/music are the biggest ones as I remember).
From the subs I did read before it all started they stated that they would start for 48 hours, evaluate their stance after and behave accordingly.
I would be suprised to see every sub just go public again after 48 hours and go on as nothing happened.
There will be subs that will do that though and I wish those good luck for the future, but I am sure a portion will protest further in 1 way or the other.
I would like to say to please DO post these kinds of things if you indeed like a product or service or whatever.
When I am deciding on a purchase I also liked to look at reddit threads at what the experiences are from the people who already purchased the service/product.
I would scan the threads and also look at how many people just agree with a point that is being made.
It is moronic to say that things like that isn't "contributing", it actually also helps me as a consumer decide on the purchases I make and not all the comments have to be eloquent about it.
