There is no grand secret conspiracy. Why? The more people involved in a conspiracy, the more likely it will leak out. A conspiracy between two people may never get it, a conspiracy between a hundred people will have someone slip up in a few years at most, but an international conspiracy involving millions of people with disparate interests wouldn't stay secret for a second.

What we're seeing isn't a conspiracy as such. It's a conversation happening in the open about "business models" and "revenue streams". It's also based on customer expectations. There are definitely markets out there for the repairable, buy it for life goods, but there's just not nearly as big as the customer who upgrades their phone every two years. But obviously that's going to be different for diabetes. Reliably being able to repair pancreatic cells would be huge. If the companies selling insulin tried to internally stifle research to avoid cannibalizing their insulin business, other companies have an enormous incentive to take a crack at it.
