You’re right, but not in a anticompetitive way, simply as that! Anyway, court around the world will take care of this and fix it up by enforcing sideloading and third party payments and also opening NFC.There were others, but they were so crappy that they failed. Microsoft windows mobile on a Dell X5 pocket device, Blackberry, but was aimed at business, not consumers. You can't simply just make an OS. You need to build an ecosystem behind it as it's not the 80's anymore and that is why Apple and to a point Google are where they are. I can take a picture on my iPhone and it will be available on all of the rest of my Apple world, I can pair and put in a pair of earbuds and they now work with all of my Apple devices automatically, etc.
