DrPloxoYou bring up a good point. The majority or a vocal minority dislikes the map. This could be because full uber-advantage and a full wipe means you get to chill out and watch for 4 man suicides for another 40-50 seconds. It could also be because you wait around for a minute or so while they go cap A. Who knows. But the consensus seems to be that the format is not suited for maps that don't have reciprocation for failed pushes.
I like how you complain about waiting for people to cap A when it takes 10x longer for people to get into the server than that and setup time combined. It's no better than people waiting at last for the other team to push except there might be a pick (and hey, pushing teams run spy/snipers from spawn at the start too, so it's not like nothing happens).
Also, push maps also have people suicide when their medic dies and they need to even the advantage. Only difference is that medic can safely charge.
Finally, failed pushes cost time, something that matters a lot in a stopwatch/time trial game mode. Attackers always need an advantage so that they can actually get a time. It'd be fucking stupid if the attacking team got any further penalty aside from losing time.
The consensus is something only you came up with on your own.
