The "FAANG" (Facebook, Apple, Amazon, Netflix, Google) are now near a monopolistic position in their core areas and they are using it to make extra profits. But the are winds of war, e.g. Apple disallowing
segmentation for Facebook and Google or charging in in-app purchases to third parties.
Events such as these have occurred for awhile now.

A motive behind these aggressive measures may sometimes be identified.
Microsoft owns and runs Direct X which is a direct competitor to OpenGL. Which was their motive for dumping OpenGL support.
Apple owned internet video and audio codecs which were competitors to adobe flash. Which could explain their motivation for dumping flash support.
It may be too early to identify apple's motive for these moves. Perhaps in the days to come things will become clearer.
On a similar topic, there are always discussion why Apple does not use it's platform to build a search engine to compete with Google. Some think that Apple clients actually do want google to be their default engine, some people argue that Google is technologically dominant. My take is that for now, there is enough open market to grow for all the giants, but when that shrinks it may be open war.
