Bogus. The tool only needs to contact Microsoft when it changes state in some way (e.g., when it concludes for the first time that it is running on a pirated copy). I see no legitimate reason for it to phone home every day.
Further, I see a serious problem here with computers containing records that are required by law to be kept confidential (such as university computers with grades on them). We don't *know* whether it's sending any of our confidential data to Microsoft. We fully believe it is not, but all we have is Microsoft's word and we can't testify to it ourselves. We aren't authorized to just trust Microsoft on that point.
