This removes their duality of being a media / service play. This is highly beneficial to Twitter itself as well as to a new service/platform aiming to be a pure microblogging piping service. The only loser here are the Twitter app developers and startups which are faced with a now limited channel to promote their apps.

I don't see how this benefits Twitter.

A large amount of users rely solely on a dedicated third party client. If those apps lose the ability to provide the same reliable service, then Twitter (as a platform) will also be affected.

"Only" 23% of users.

Still, I could see the argument that some users are better than others and the most engaged ones are more likely to get a third party client.

Which means either Twitter loses those users eventually or coerces them into using their first-party offerings.

Existing clients are grandfathered in, as far as I can tell from Twitter's blog post.

It will coerce/force a % of users to use the 1st party apps. It will also allow them to focus on media platform features without the distraction of pleasing 3rd party devs (at the moment). I am pretty sure they will improve that side AFTER they have finished being a destination platform.
