I actually wanted to do SAToverIP as well. By now, however, I’m at the point where I will save myself the trouble. Nothing comes on TV anyway, and the current model will be replaced by streaming and similar methods in the next few years. For something like football, you can buy Zattoo or Waiku for a day or, if necessary, use DVB-T2.
But you have to consider a few factors here. The TV stations won’t disappear so quickly just because of GEZ or something similar. Even if the private channels eventually charge everywhere (they already do for HD, but not (yet?) for SD), you still have X public broadcasters. Also, for example, with me, the maximum DSL speed is 16mbit – and that has been dragging on for almost a year now with the infrastructure development. The fewer services (TV, phone, internet) that have to run over this line, the better. That’s why I’m glad to "offload" TV to my SAT system. That way I have more bandwidth overall for internet and phone.
Regarding DVB-T(2): You also first have to be within the reception area. Since we still didn’t have internet and I didn’t want to know anything about a SAT dish for a long time ("I don’t know it, I don’t want it"), DVB-T (without "2") was our emergency solution. Well, what can I say: On the ground floor, the 50€ indoor antenna didn’t find any channels, and on the attic floor by the window, with some luck it got ZDF and a few third-party channels (SWR, hr, ...). The private channels aren’t broadcast at all.
With DVB-T2, the private channels are supposedly going to be broadcast, but it will be chargeable (if you believe the current freenet advertisement). However, you first have to be able to receive it in terms of coverage.
You may be right for your special case (maybe you have a 200mbit connection and live in a DVB-T covered big city), but I definitely cannot generally agree with your statement.
