You may be talking about the "free sample of limited gameplay" or "free to play, pay to win" or "free to play, pay to not wait" models, to all of which I would deny the simple title of "free to play." A good example of actual-free-to-play is DoTA: You get access to the full game, all characters, all servers, etc. The only thing you pay for is cosmetics; you can't buy anything that gives an advantage in-game, and it's hugely popular as an esport and makes Valve tons of money. It's free-to-play done right imo.
