Only Apple?

Lina Khan's name isn't mentioned by the OP, but it's likely that her fingerprints are all over this antitrust lawsuit.

Anyone who's aware of her views and actions must know by now that Amazon, Google, and other dominant tech companies are on her "naughty list" too. (Khan first rose to prominence while at Yale's law school, after writing extensively about Amazon as a new kind of monopoly.)

I'd be shocked if we don't see more antitrust lawsuits initiated in the coming months.

would rather see Amazon or Google first

Dont worry, it will be dropped in October or so as long as Apple takes a hard look at what disinformation is allowed to be viewed on iDevices.
