forced exclusivity and bigger cut of sales to studios is still more money going to developers tho, regardless of how heavy handed the tactic is. its kinda dirty but its not as unethical as people seem to make it out to be. no matter how heavy handed the tactics are, if epic games' launcher is garbage, people will leave after some time or bypass using the launcher (eg externally launching the games and only using the launcher to download it). these exclusivity things arent permanent either, as apparent when devs promise to release on steam a year later (probably after their exclusivity contract with epic is up)
i believe in the invisible gamer hand of the gamer market in determining if epic will survive after it stops doing these forced draws to their platform. they cant do this forever (as its not very profitable to give away money and also promise a bigger cut than steam) and savvy devs will demand larger payouts to be exclusive going forward, due to all of the negative media attention surrounding exclusivity announcements
