I think it's pretty easy to argue it would have been overreach by a regulatory body to block the deal.

It's difficult to guess, with reasonable certainty, if the deal will kill all competition. Difficult given the competition that is out there on all fronts (Steam, Playstation, Nintendo, Epic).

So if it's not totally clear the deal is bad, it's overreach to block it. Layoffs and increased pricing isn't indicative of monopoly power. Lina's mandate wasn't to prevent layoffs, it's anti-trust. It's also too early to conclude anything from the deal that was closed so recently.
