I mean, the short answer is "no." But the longer answer is more complicated than that. Start off with the question of, is the consequences of not being able to access your device worse than the consequence of someone else getting unauthorized access to your device (or is it worse, controlling for the probability of each?) And then, is Microsoft's storage of those keys more or less secure than any alternative way you could back up those keys remotely? It's possible to both not trust Microsoft to store the keys safely and to make a rational decision to entrust the keys to Microsoft anyway.
