And yet that is precisely what is happening. Shimano is stonewalling. They are quietly replacing broken cranks under warranty but resisting the call for a recall. They have their financial reason for doing that. But why are you making excuses for Shimano now?

There are a LOT of cases of these there, even if a few of those pictures were duplicates. And that is just one hashtag on Instagram. There are doubtless many more people who suffered these defects, who are not on Instagram. Keep in mind that these cranks are all 11 speed and up. Meaning they are all still fairly new- under 10 years old . Those glue joints will only get worse when these cranksets get old. The pro tour teams throw away their bikes every season. Do you have that luxury?
Also- in terms of volume, the low end groupsets way outsell Ultegra and Dura Ace. Nowadays a Dura Ace equipped bike is like $10,000. Very, very few people buy bikes that expensive. Most people buy Sora / Tiagra / 105 type bikes. That is why what you are seeing with these Ultegra/Dura Ace cranks breaking is very alarming. In the C&V section people always bring up the 'Ishiwata death fork', AVA death stem, 'impaler seatposts', etc. Here comes another one- Ultegra and Dura Ace death glue cranks.
