Suffice it to say, the changes are disappointing, and Chris O'Neil's response seems like it was more about damage control than actually listening to the response from long-time paying customers. I too purchased a premium subscription within a week or two of trying the free version back in 2009, and I too have watched it morph from a brilliant tool into a bloated app with lots of useless features (work chat, anyone?) that I would never use. Granted, there are a lot of useful things that have been added to EN over the years as well, and I'm sure there will be more, but at what cost?
They broke the trust of their users. That alone will surely make paying customers think twice about whether or not to continue paying, and it will certainly prevent educated consumers from signing up for a new subscription in the first place.
