This would have been less of an issue if it remained enforced from the start. Re-enforcing it after demonstrating it clearly works without makes it look scummy and greedy. People could also easily refund if they didn’t agree. Now its too late.
For a lot of people it now looks as: now that the game is a success we want to collect everybody their data as well so we can make even more money.
Tbh, other games just require a 3rd party account without linking them explicitly. This requires an actual link which ( likely ) gives them access to a lot of your steam information which you’d rather NOT give to a corp that doesn’t seem capable at guarding people their data.
