This is extremely condescending. Nobody is having a political negotiation strategy session here. Evernote's (and its developers') livelihood is developing and maintaining a product with certain uses and functions, and they've chosen to downgrade their product with a half-baked unfinished update, after ignoring all the beta testers "arguing the merits of their position". If they reduce functionality, the people who used those functions *should* cancel their subscriptions. Purchasing a service is not charity, it's commerce. Calling it unfair for people to not want their money going to a company that no longer does what they pay for is absurd.
Why in the world would anyone who doesn't work there care about the app? People care about what they use it for, what they are able to do with it. I don't care about the app itself anymore than I care about a browser or word processor; I use the one that best meets my needs. If Evernote no longer does, people will leave. Doing something in a mutually respectful manner requires respect from both sides, and I'm not seeing that from Evernote.
