Lol, not sure how you can be disappointed in Apple, they haven't done anything. This is a rumor on rumor site. If Apple did decide to delay then it would be presumably because they realized from feedback from developers that a few months isn't enough time for people to update to such a massive change. When Apple ignores dev concerns people criticize them, and in this rumor where they would be potentially delaying to allow devs more time to update they are also criticized. Remember that titles on this site are editorilized to get as many views and comments (which results in more views) as possible since MacRumors gets money from all the ads.
So let's all take a breath, and be grateful that Apple continues to add more privacy features every year where others do not (until they are forced to after Apple does). Apple does a lot of a questionable things that deserve scrutiny, but Apple's continues progress on privacy is quite welcome.
