Actually, there is. Simply accepting the benefits of this systemic injustice and not actively working to remove it, especially when in a position of power, is not acceptable. If you just use white privilege to live the best life you can, that is participating in the system and is not correct. You have a duty to not only disavow 'white preference' as you call it, but also remedy the inequity of your privilege, not simply use it.
It's pretty simple why Twitter would discontinue this app. They want to have a consistent user experience across all their clients and they will continue to introduce more rich content (such as Cards) from their brand partners. It's a lot easier for them to manage this consistency of experience by sticking to HTML5 for the client experience rather than maintaining and updating a set of native clients each time newer content features are released.
All these articles claiming Twitter is restricting developers using their API are all missing one important distinction: Twitter is only restricting Twitter client developers. There are hosts of other developers who are using the Twitter API with no restrictions, those building value add services in Social CRM (social media monitoring, analytics, data reselling, sentiment analysis, etc). Yes, Twitter's new ecosystem is geared towards the B2B market. But to say they're restricting developers across the board just isn't true. However, it seems most of the tech blogs tend to think only of consumer-facing client apps as the members of the Twitter ecosystem, and so forget about all the other apps out there, the ones they're not restricting.
