I looked myself about 6 months ago and it's not clear whether that's true or not.
Which probably doesn't bode well for AZDO as it's not a definite no, but on the other hand it's not clearcut that they are actually pushing that.
The general consensus among the great unwashed is that AZDO is turning into an undead project that won't improve. But the reality is there's a lot of present enterprise investment in AZDO and no clear migration path, as well as a lot of internal MS use of AZDO, so it's doubtful it's true but more a loud PM in GitHub over egging his own product.
But it's sort of turning into a self-fullfilling prophecy as people are getting skittish about investing in AZDO.
The reality is that unless you have crazy builds switching is a few days work and more a pain in the ass than a real project.
The whole design of AZDO is Enterprise-focused, and for example you have the capability to customise every little thing. It has a plugins API so you can add renderers for custom file formats.
The design is such that even if you have 100 active repositories, it is easy to use.
GitHub has no such vision. The interface is clean and easy to use, but the depth of customisation is nearly nonexistent. And the interface keeps bringing you back to the public area of GitHub.
Would be very disappointing if they killed off AZDO. I don’t think GH is an alternative, at all.
Do they really want to move users off Azure DevOps to GitHub?
Asking as someone about to invest in AZDO.
