It's a different topic because the OP dispute (whether to give credit to data generation/creation as comprehensively as to data analysis) is logically distinct from the OP dispute (whether to give different amounts credit to the same sort of contribution based on where/whether it was formally published). The fact that the people you criticize continue to not properly give credit even when a formal publication exists demonstrates this starkly.

For what it's worth, I agree with your criticism.
