Even though Early Access can be an incredible thing to allow developers to build up their game with the community, and pull in some early funds, it can also go very wrong. And now Valve are making it a bit clearer for you if a game hasn't been updated.
While I’m in complete agreement, and I’m a huge fan of Beam (originally bought it before it was even on Steam), at some point you need to draw a line for full release, and anything beyond that is feature creep.
I think it’d be good practice for everyone to have a time limit in place, since the long term EA games that turned out well are more outliers than the norm.
