Is twitter removing the oxygen from its ecosystem?

On 20 september 2012, Linden Tibbets (CEO IFTTT) emailed the IFTTT-community that they will be removing all twitter triggers from its service in order to comply with the new guidelines by twitter. An extract from the email:

In recent weeks, Twitter announced policy changes* that will affect how applications and users like yourself can interact with Twitter’s data. As a result of these changes, on September 27th we will be removing all Twitter Triggers, disabling your ability to push tweets to places like email, Evernote and Facebook. All Personal and Shared Recipes using a Twitter Trigger will also be removed.
*These Twitter policy changes specifically disallow uploading Twitter Content to a “cloud based service” (Section 4A https://dev.twitter.com/terms/api-terms) and include stricter enforcement of the Developer Display Requirements (https://dev.twitter.com/terms/display-requirements).

Is twitter afraid of app.net? or just worried their ecosystem is not generating enough revenue yet? Or is IFTTT too fundamental about this? Could IFTTT comply with these guidelines by only excluding some specific recipes? I don’t know. But I do know most of my IFTTT recipes are using Twitter. For me the ecosystem will be loosing value on on September 27th.

In the past Twitter has been the Social Network known for its “openness” towards users as well as developers. But apparently Twitter no longer wants to be a “Protocol” or an “Interface” but prefers to be the “Application” or the “Community”.

I’m still wondering whether this strategic change will be beneficial for the total ecosystem, or Twitter in particular.
