You are missing the forest for the trees. I don't see many (really any) people saying that AWS went against the license terms. Simply that their actions do not benefit these projects in any proportional way which they rely on heavily. I'm sure many of these projects would much rather just have more collaboration and support from AWS than to have to think about and deal with a major player being a bad actor.

Edit: I am much more talking about projects like Postgres than companies like Elastic.
