I understood perfectly fine... You presented a previous timeline of the analogue to digital transition, which took over a decade longer to complete than originally proposed, as a precedent of how the ATSC 3.0 transition will unfold.
What you failed to factor in was DRM and the incentive it gives to broadcasters to expedite the transition. DRM is now a tool they use to discourage anyone from watching FREE local broadcasts. In essence they are sending OTA back to the 50's... no recording, time-shifting, place-shifting, or commercial detection.
Broadcasters will monetize ATSC 3.0 in any way possible and make FREE OTA as difficult and confusing as possible with the goal of pushing the final 10%-15% of users to a paid product. To ignore that and pretend that this is the digital transition all over again with another 10-15 years of ATSC 1.0 shows a complete lack of understanding of the situation and driving forces behind the change.
