Perhaps for some. Others might realize that humans make mistakes. Marco overreacted; there is no question. He made a poor decision. This is not something I am aware of him having done with regards to Instapaper at any other time (I could be wrong; I don't follow Instapaper super-closely, but I would have expected to see it here like this one).

So a first mistake, with a reasonable explanation, a sincere apology and a promise not to repeat (my reading; yours may differ) is "too little, too late"?
