I would not say these very large and engrained services are "ripe for disruption" unless you totally revolutionize the feature-set of such products. I think things that are ripe for disruption are things like traditional IRL services...like how Uber is greatly disrupting taxi services, for instance. I would like to see disrupts in grocery stores, point-of-sale systems, and other tangible services that can be revolutionized with new technologies. I think disruption is more about an industry than taking on a single company.
