Eve Online seems to now have it as free to play - to a certain extent:

The Alpha accounts are really just continual versions of their old 14 day trial accounts, with the same limitations on skills and ships. The Omega accounts are the standard full access accounts which have to be subscribed to. Sounds like they're aiming for the Korean grindfest style of gaming with that. It's still a massive time-sink. I stopped playing it a couple of years ago and have no intention of going back to it (can't even remember my account password even if I wanted to).
But they had no choice but to offer a free to play version. That is the current model for online games right now.
