Microsoft charging for Windows Live Mobile Messenger?

If you use a Windows Mobile device, you might have recently been issued a warning that you have a 30-day trial for your Windows Live Mobile Messaging service. While this would be fine if there were some sort of statement from Microsoft regarding a change in policy, it seems that this message has popped out of nowhere, leaving many people bewildered to whether Microsoft will now be charging for the messaging service. The trial warning reads as:

7.4 Trial Period Offers. You may have received a limited time of free service or some other trial period offer. Unless we notify you otherwise, if you are participating in any trial period offer, you must cancel the service by the end of the trial period to avoid incurring charges. If you do not cancel your service, and we have informed you that the service will automatically be converted into a paid subscription at the end of the trial period, then you authorize us to charge your payment method for the service.

More on this as it comes.
