Microsoft. That should be enough cause for concern, really.
The funny thing, though, was that it didn't provide any sources for that second response. I pointed out the discrepancy and it told me I was right and here are some sources and provided yet another unsourced summary of how Microsoft was great, basically writing its own sources itself. When I insisted twice more using different wording and requesting no primary sources it started retconning its arguments, but all the sources were from microsoft.com regardless. It was all very ironic.
It is seriously annoying when it does it. Probably the weights of what they want to have happen somehow get shoved in there and you have to basically prune them out one by one to unstick it. Simple statements like 'that seems to be wrong' do not unstick it. You basically have to say 'remove all references of XYZ from this conversation and do not bring it up again'
