I don't buy the argument that having a bunch of vendors extend the ISA makes it more secure. I think we would end up with an ecosystem with a lot of custom extensions and functionality that will end up exposing more attack surfaces and that would make it difficult to know if your device is affected or not.

You are highlighting the risk of fragmentation causing security problems. I think that's valid.

I think a lot of people are talking about "closed source" security as in nation-state level actors and "backdoors": https://www.csoonline.com/article/3220476/researchers-say-no...
