Early Access is an extremely bad business practice and should be stopped or limited to what progression is on a game. I very, very dearly consider how far a game's progress is along with if there's a road-map for development and stuff like that. If there is no road-map, I will not even look at the game again until a few months down the road 99% of the time. The 1% chance is for Steam friends who tell me that the game is good. This has happened with 7 Days to Die, along with Prison Architect. I am also considering TUG but everything else I've seen just screams "We don't know where we're going, but we want your money!"
However, I do agree with the sentiment that the term, "Early Access" is definitely code for, for most games, alpha. In my opinion there are only a few games right now that qualify for a "beta" tag, in my opinion. There are definitely certain criteria that need to be met before considering something a "beta", and most EA games on Steam do not match this criteria, unfortunately. And a lot of them suffer from lazy developers who only push out an update once a month, if not once every two, three, several months. I understand life issues, but when you get money from people who purchase your product, you're telling them that you are going to be fixing up your game and pushing content and updates frequently. Frequently to most people means, in the early stages of a game, or in general in the "alpha" stages, probably a few fixes a week to maybe one update per two weeks, consisting of content and bug fixes.
Anyway, I am not okay with Steam allowing Early Access titles without certain criteria to be met first to be released onto Steam. And with the Greenlight service being taken away soon... well, it's gonna be havoc.
