Quite frankly, yes. It seems that Mojang are dragging their feet on this, and from looking at what people (legitimate Microsoft accounts) are saying about being unable to access certain MP servers, then absolutely yes. The job of policing cracked accounts should be on Microsoft, not places like Technic. If Microsoft gave effective tools that allowed legitimate players access here, then this idea would never have crossed my mind. But at the minute, again, absolutely yes.
