It's not actually that concerning. RN's pods are vended via npm not trunk so trunk going read-only will not have an outsized impact on RN.
The risk is that over time Cocoapods will no longer work to integrate dependencies with ways Xcode wants them to be.
Switching to SPM is a massive undertaking for a large project with many intertwined dependencies and configuration options. It's far less configurable than Cocoapods with basically no scripting options during install.
I think the most concerning part is all the third party libraries already on life support or already abandoned a few years ago will all die during the switch.
There is no dev community. Is there a developers organization (unions if you must) which fights for minimum pay or work standards?
No there's not in fact it's actively frowned upon because if salaries are standardized no one will get to enjoy those huge faang pays. It'll be averages. That is not the capitalist way.
You're doing the work highly paid facebook and vercel employees are getting paid for.
It does, in recent react native versions they show a deprecation warning when running “pod install” directly which is probably a signal they are working on moving to other package managers, but not aware of what the plan is.
