Companies like Sonatype would be an issue since they are owned by USA private equity. We would not give "Vista Equity" access to anything with the current EU US relationship. It's bad enough that we're so tied into Microsoft, which the EU might task us with leaving if they deem it critical enough for the security of the European energy sector. That's a risk we live with though, there isn't a realistic alternative.
That being said, our current strategy is more along the lines of building thind within standard libraries. We really wanted to adopt Go company wide, but it's proven impossible for non-SWE staff to use AI to create their projects in anything but Python. So instead we've created AI configurations that know our security policies, the tools we want them to use and we've setup security policies which won't even allow you to run a Python executionable inside a virtual environment unless your devices is sepcifically allowed to do so in that specific folder. Similarily we've completely limited what VSCode extensions they can use down to the named folder version. Which sort of sucks, and I doubt a lot of it would be possible if it wasn't because the c-levels are personally liable for security under EU law.
We'll see what happens after september when the summer holidays are over and the real token cost of AI will kick in.
