Valid point. I think people are turning this into a 'crusade' partly because they are just shocked and appalled by the way Reddit handled this whole thing.

In the end, it's their site and their decision to make, but it's understandable many people are upset by their actions and no longer want to use the site (which, btw, even if you were using it for "free" you may have been contributing in other ways via posts, comments, moderation, etc).

It also means losing potential customers - I would have been willing to upgrade to Reddit Premium to continue using Apollo, for example, but now I wouldn't even consider it.
