Minecraft is a multiplatform game Microsoft brought for a fuq ton of money.
Microsoft do not want to cut off sources of recouping that money hence, not only did PS4 get Minecraft, it got:
Minecraft Story Mode Episode 1
Minecraft Dungeons
Minecraft Story Mode Episode 2
I just spotted there are 3 paged of minecraft stuff on the PSN store, so here
Official PlayStation™Store UK
A full complement of all NEW content on PlayStation consoles.
You keep telling yourself it's not coming out on other console platforms if you like, keep believing MS are in it to get another million console sales, rather than get all that money from PlayStation and Nintendo gamers if you like.
I'll still be here when the reality kicks in for you.
Not to mention Phil has already said I believe that they didn't buy Bethesda to piss other gamers off.
Money is money, MS think the most money is in a subscription service, would Netflix be anywhere near as successful if in only worked on Bravia's and would Disney plus have anywhere near the subscribers if it only worked on LG TVs.
Microsofts ultimate goal is to make money, you might care where it comes from, they do not.
