Antitrust suits result in more varied options than just breaking a company up. Microsoft had to have certain aspects of it’s operations supervised by the Department of Justice for years, and had to make mandatory changes with respect to browser bundling that only ended with Windows 10/11.

Intel has settled some antitrust actions – namely lawsuits by AMD – with money and cross-licensing agreements. They’ve spun off some divisions and operations over the years but none forced that I can recall.

Depends on what you mean. It’s a more arduous process – but even if this injunction were granted that process would still play out unless Microsoft just decided to give up. But in another sense it’s not as high of a bar to reach as a preliminary injunction, which the court by process has to make certain assumptions with a presumptive bias towards the party not seeking the injunction.

This is just the fight for the preliminary injunction. The FTC can still use antitrust proceedings to prevent/unwind the merger.

Didn’t the theatrical cuts release with the first DVD sets well before the takeover? (Albeit yeah, that’s 480p.)

You also can't sell it, and thus also can't buy it used. This is the final move to end the used market for console games.
