It shouldn’t be when they were talking about making that shit retroactive for games that were already released. Unity proved they cannot be trusted. Besides, developers should move to other engines for the sole reason of sending a message to the other guys in the industry like Epic’s Unreal Engine. Pull shit like this and you’ll lose out on the developers. Make them realize that Unity was a failed experiment and no one wants to be like them.
This has been the case for Google Voice. I transferred my old number to it and even stuff I had it for verification no longer works because services see it as a landline for some dumb reason.
*note, this isn’t for all online services. Some still recognize it and accept it for verification. But a good handful don’t.
