The test for antitrust is competition being reduced to the point that prices can be controlled with monopoly-like behaviour, or suppliers are cut out from supplying competition.
Applying that test to all of those companies doesn't give Apple supplier control, extensive pricing control or monopoly power in any market.
for eg. even acquiring HP would be total 'PC' market share of ~25%. The only one that may be a concern is ARM, but that doesn't mean mergers are stopped, it just means that agreements are reached (for eg. as with Google and ITAR)
