As in why don't they mention Azure by name?
Or as in there shouldn't be isolated silos?
Like imagine if AWS was composed of separate companies for different services - Fargate was an Heroku acquisition say - and then they all went down and blamed their 'upstream provider' because they can't work without say VPC or EC2 availability.
I think that's all GP meant, it just reads a bit funny, not that it's wrong.
