Isn’t that what Google did with their messaging things? Wasn’t the same app as SMS?
Isn’t that how they’ve deployed RCS?
The MS case wasn’t all about defaults. I’m not sure any of it was about defaults. The thing that killed them was deals saying you couldn’t offer competing programs or had to pay them regardless of if you put Windows on the machine (so it was a waste of money to ship anything else). Plus changing code to break competitors.
Google doesn't have "messaging things" anymore. The default messaging app supports SMS/RCS and that's it.
They tried the unified SMS/proprietary message protocol approach with Hangouts but that was short lived. I'm not even sure if it was ever at any point installed by default on a majority of Android phones.
After Hangouts, they tried Allo which did not support SMS and was not a replacement for the default messages app which did support SMS.
