Hmmm....never knew about that Star Link plan. For comparisons the cheapest home WiFi plans start from $35 monthly from the larger internet companies in the USA like Spectrum & ATT&T etc and their lowest speeds are from 300 MBPS.
SpaceX has dropped its 'Residential 100Mbps' plan from Starlink's US site. This sudden change likely stems from high demand filling up network capacity in the areas where it was available. However, the plan is still available for users in Australia and Canada.
