The problem more generally seems to be “I'm locked into proprietary services that don't allow me to use libre software”. I suggest that those services therefore aren't very good.
If libre software fails to compete with a proprietary alternative in terms of features, it's reasonable to criticise the libre software. Similarly, if a proprietary service fails to compete with a libre alternative in terms of choice of how you use it, it's reasonable to criticise the proprietary service.
