I am behind the curve on this one. A server collecting telemetry per se is only useful if it can send that data back to base. Most production servers I've seen could not talk directly to the internet or send external mail.
No matter what Microsoft does internally they can only simulate what their customers actually do. That telemetry data can be a mine of information and flush out problems so they can be fixed early.
I'd be curious to know from those who have experienced various levels of paid support from Microsoft and other organisations how Microsoft rank.
I've been quite impressed with both Microsoft and AWS. Neo4j and DataStax were reasonable and certainly better than I expected given the size of company.
