Nothing becomes any more closed if you switch the ISA of the CPU used in your VPS to aarch64. The only closed ecosystem here is AWS itself, but what takes power away from you is using non-EC2 services like DynamoDB.
In fact the Arm ecosystem is way more open, because there are SoCs that can run completely blob-free firmware (e.g. from Marvell), which is just not happening with any modern Intel/AMD system.
