Ironically this is the only thing preventing a chromium monopoly with probably >90% of marketshare (Although this restriction is still not that great for the user)

so if this restriction was gone, it would make everything more sane for customer, while finally dealing with chromium monopoly.

sounds like a win-win to me.

How would a chromium monopoly be a win (for anyone but Google)?

I think the poster was thinking it would make Google a clear monopoly, making an anti-trust case easier to pursue.

exactly this.
