Is this blog post a legally enforceable contract? Is Microsoft specifically indemnifying all users of Copilot against claims of copyright infringement that arise from use of Copilot?

The blog post says that "there are important conditions to this program", and it lists a few, but are those conditions exhaustive, or are there more that the blog post doesn't cover? For example, is it only in specific countries, or does it apply to every legal system worldwide?

What guarantees do users have that Microsoft won't discontinue this program? If Microsoft gets kicked in the teeth repeatedly by courts ruling against them, and they realize that even they can't afford to pay out every time Copilot license-launders large chunks of copyrighted code, what means to users have to keep Microsoft to its promises?
