The one concrete claim you made was:
There have been several sales in a row now where
Play/Epic titles were discounted while Steam keys were
either unavailable or full-price.
I honestly don’t understand how that could be true when this is the 2nd Epic sale of Primal, and there have been none between this and the last Steam sale. Maybe you could explain it rather than resort to insults?
It was priced at $14.99. That’s the price that Ubisoft set, that was the price that was shown on the front page, and that’s the price that Ubisoft’s revenue from these sales was based on.
Now, to a customer that breakdown doesn’t matter, they’re just happy they got the game for cheap. To companies it does matter. And your initial post wasn’t phrased from the point of view of a customer. Instead you said that "Ubisoft games now have a Steam Tax” and that “they are aggressively flexing against Valve”. And that’s the part that I disagree with. As far as I can see Ubisoft has been running sales on both stores at a similar frequency, and has not been setting higher prices on Steam.
Just what is the tax? Ubisoft is imposing a Steam tax because Steam isn’t throwing money into a similar sale?
