Thank you for your feedback, and of course we are sorry that you are disappointed at the decision to change the way our embeds are displayed. With so many users and such a wide variety of expectations and use cases, it can be challenging to keep everyone informed, and satisfied with our updates.
To reassure you, before we make any change of this magnitude, we conduct exhaustive experiments and data studies to confirm the impact. In this case we concluded that the update was positive for the broadest possible base of our users, and for people encountering Tweets in the wild. Naturally, you may have a different opinion based on your experience with the platform - I have been a Twitter user for 11 years myself, and changes are sometimes not what I might have expected from back then!

There are no plans to revert this widgets update, so you should assume that the new format for embedded Tweets will remain the common way to encounter them via our web embeds for the foreseeable future, until such time as we may look at further enhancements. As @kltelles mentioned, it is perfectly possible to continue to interact with embedded Tweets, although with one additional click to the app or website.
Thank you for your passion for the platform!
