CS was paid, Dota and Fortnite had “early access” packs before being released. Yeah fortnite is the odd one out here with keeping early access stuff to seperate gamemode and still costing money, but was originally planned to transition to f2p.

3/5 games from that list also launched as paid games, but gained majority of its players after becoming f2p. Yeah people love free stuff ¯_(ツ)_/¯.
