Your statement is contradicting with stating it was Purposely built for Azure.

Someone would have to make a Ubuntu equivalent and use Azure Linux as the base to turn it into a general purpose Linux OS.

Personally, I don't trust Microsoft and their Linux distro with how they Enshitified Windows OS and all of their other software products. Add in the fact that Microsoft likes to multi-count CVEs, per distro, instead of the actual flaw to try and make Windows OS look better when it comes to security.

Microsoft is a bad actor.
