Remember Quibi?

All the money in the world can't actually turn a turd into a market leader.

If you have a good product you have to play the marketing game to avoid getting left behind. If you have a bad product you try to play it and you still don't get picked up. (This last bit is where things usually turn into an argument about "no, obviously [this thing I don't like] is bad and is only popular because of the marketing", which assumes taste is more universal than it is.)
