Samsung smartphone chips and NXP are not targeting the same market, so it wouldn't mean playing the same strategy.
NXP is making chips mostly for industrial and automotive embedded systems, most of which are running either some kind of real time OS, or Linux through Yocto where you need some good support.
A lot of companies are releasing i.Mx modules for easy integration in products (Toradex to name one, but a lot other if you search a little), not an ecosystem that really exists for Samsung chips.

And it is not the first time a company wants to buy NXP, last one was Qualcomm, so no need to be scared yet for something that may not come before a long time if it really comes...
