It was meant more to make everyone uncomfortable. I think a lot of people are all going to feel uncomfortable being put in a situation where they might need to overtly praise Microsoft for contributions if they climb up to be a notable ranking in the list of corporate sponsored contributions to the linux kernel. I'd much rather see Canonical stay ahead of MS in the regard, but I don't make Canonial's staffing decisions. The irony is, Canonical stands to benefit with better hyper-V support in the mainline kernel. I wonder if there is any money to be made supporting Ubuntu guests running on hyper-v. So we might even find that Shuttleworth will have a compelling reason to praise Microsoft for their kernel contributions. Man that would be really uncomfortable to watch happen.
